Some Work, All Play

Our brain juices were really flowing on this great episode! The main story came from the pro peloton in cycling, where athletes are pushing the limits of carbohydrate consumption during hard races. In general, teams closely monitor fueling to get athletes to 100-120 grams of carbs per hour (400-480 calories), and there are hints that some are pushing the limits even farther. What can we learn? Our theory: "food doping" is not just for the pros, it's the way for all of us to access our greatest strengths and make hard training healthier in the process. Yet still, somehow, this is an unsettled area for runners. We bring the heat with our spiciest thoughts on performance fueling.

It's really hard to summarize this episode, so we'll just say this: as soon as the recording stopped, we agreed that it was the most fun we have had doing one of these. You probably know what that means... so many weird and fun discussions! Other topics: Josh McDaniels getting fired from the NFL as an excuse to wax poetic on ego-driven coaches, why the sports world has so often celebrated coaches who are bad people, what lessons there might be for leadership generally, why we love when athletes race as often as possible at shorter distances, our endless Halloween, a debate on candy flavors, the most incredible story from the US Trail Half Marathon Championships, a cool new study on timing of iron intake, NYC Marathon stories, Strava DMs, how to think about MRIs, and hot takes.

Our takes are like our crop tops and like all of our listeners. They are HOT STUFF.

We put on some dinosaur onesies (our business formal) for this awesome Halloween episode! The big discussion was on UTMB's controversial announcement of a new race in Whistler, Canada, on the same weekend as the now-discontinued, grassroots race called Whistler Alpine Meadows. UTMB rode the sport's wave of exponential growth, gobbling up races to incorporate into their World Series. When Whistler Alpine Meadows was denied a permit, they swooped in and plopped a corporate race in its place. It's a fascinating mix of business strategy, economic models, relationships, and culture, and we try to break it all down in a nuanced and empathetic way. We accept that a rising tide lifts all boats, and we acknowledge that we benefit from it. But if that tide destroys the smaller boats (whether through intention or mere negligence), we need to reject that thesis of unrestrained growth. This could be a turning point in the future of endurance sports, and the community has the power.

Before getting to UTMB's big blunder, we talked about training intensity distribution through the lens of a new review study! Across sports, endurance approaches coalesce around similar intensity distribution numbers, whether the sport involves the pool, the snow, or the trails. How wild is that? What are we seeing? In that convergence, there are lessons about how you structure your weeks and think about long-term growth.

And there were so many other fun discussions! Topics: heat training via Halloween costumes, the sexiest dinosaurs, our feelings on ghosts, 2 show recommendations, the importance of easy training and how that influences weekly structure, why workout design may be less important than you think, speed development, a recap of Big's Backyard and Harvey Lewis' awesome achievement, the Javelina 100, and hot takes.

We brought some Big Party Energy to this great episode! The main discussion revolved around different ways we put research into practice. This weekend, David had one of his best races ever at the Blue Sky Marathon, and we adventure to the coolest edges of the science to tell you what we are trying! That included a deep dive into caffeine's role as a performance enhancer, particularly for fatigue resistance. Strategic, individualized caffeine consumption could be a massive opportunity for breakthroughs. Or, you might crap your pants and never sleep again. Worth it?!

We also talked about the wild, emerging science on ketone supplementation after exercise. It's hotly debated, but studies have found increased red blood cell production and reduced symptoms of overreaching with this intervention. We use the topic as an excuse to jump into the choppy waters of new science, where there may be adventure opportunities! Or there may be sharks who politely ask for more studies before experimenting with new protocols. Science sharks?!

And this episode was a total party with some of our favorite topics! Other discussions: a 3-cake birthday party, stress and health, big breakfasts, high-calorie fueling during races, year-round heat exposure, thoughts on pacing, a new study on how shoes wear down over time, continuous lactate monitoring, a rundown of this week's endurance news, and hot takes. Somehow, we end the episode harmonizing to Nelly's "Grillz." That's how every podcast should end, along with every graduation speech and most presidential addresses.

We ate a truly stunning amount of chicken and milkshakes to fuel this great episode! The main training topic was on a new review article connecting hemoglobin levels and VO2 max. Across nearly 400 studies, these variables have a strong statistical correlation. Blood volume could be primary a driver of performance, and we break down some simple ways to optimize your levels.

We also celebrated Megan's return to training after some good health news! That was a great excuse to talk about the lost art of Zone 1 training. Easy can be very, very easy (at least some of the time). Your mitochondria and muscle fibers will thank you!

And this episode featured a ton of our favorite discussion points! Other topics: energy availability and our jaw-dropping Chick-Fil-A order, developing the entire aerobic curve, 3 ways to support self-belief, an incredible story from baseball's Philadelphia Phillies, doping thoughts, our issues with prototype shoes, qualities of good coaches (and whether they need to run themselves), your watch's metrics, whether you should pay attention to them, and hot takes. One of our listeners has a disturbing view of toilet paper that you need to hear... and ignore.

We brought some A+ brain energy and some C+ heart efficiency to this awesome episode! The main topics involved the extremely eventful weeks in the running world. On the joyous side, the Chicago Marathon was a race for the history books, with a new world record and blazing fast times from US runners. We celebrate the incredible Molly Seidel, plus talk about body image, fueling, rest days, training volume, and more. On the less joyous side, we discuss a controversy from a brand's social media post about the Boston Marathon. You know the one. And if you don't, get ready for a wild ride into the intersection of marketing, social media, and unintended consequences. We break it down, challenge each other, and hopefully come to a loving conclusion... After Megan was 100% right, of course.

And this episode was jam-packed with a mix of both important and irreverent discussions! Topics: last week's heart health setback, our hope for the future, training partners, protein intake, starting strength work, the cancellation of the Twin Cities Marathon due to heat and what that means for the future, abnormal heart rate responses, how to manage inflammation, and a listener corner email that will BLOW YOUR MIND.

You want the best podcast vibes? Because that's what you get on this episode, with some 4 AM recording energy. Why were we recording at 4 AM? For the love of the game! The main training topic was answering a listener question about what excites us most right now in coaching and theory. We delve into some of the scientific history of VO2 max via a new study, whether you should do shorter races, how to think about intensity distribution, popular supplements we are intrigued by, and lots more. We backed that important discussion topic up with a silly compilation of shoe reviews. Do you want to find the next shoe for you? Start here. Then go other places too, since we are mainly making fun of shoe companies.

And that was just the start of the pre-dawn fun! Other topics: the FURTHER project seeing how far athletes can go, our one at-home recommendation to improve your quality of life, the most weird heart rate responses to stress, WHOOP's new use of AI, Transvulcania leaving the UTMB World Series, Jim Walmsley getting a golden ticket to Western States, a wonderful new study on ultras, and hot takes.

The vibes were STRONG in this episode, even though the ankles were WEAK. It started off with a fun recap of the Grindstone 100k. What happens when an entire season is built around a goal, but it all ends in some delicious failure? Setbacks can be good for the soul, in moderation. In that way, they're kinda like bacon. Even more joyous than that was a full breakdown of Jim Walmsley's UTMB training, distilling some lessons from last week's interview. He gave us so many good nuggets, from weekly mileage to workout structure to season distribution, and we savor those tasty, tasty nuggets. Now we just need to convince Jim to let us co-write "The Walmsley Method."

All-in-all, this might have been the most fun we have ever had recording an episode! Other topics: the best sports story of the year, why we want to be like cyclist Sepp Kuss, a new study on training intensity in top cyclists, the $500 shoes from Adidas that were just used to set the road marathon world record, why that record makes us feel a bit queasy (with some unexpected tangents about economic theory), thoughts on caffeine intake via a new study on sleep impacts, and hot takes.

This episode is one of the coolest moments of our lives: interviewing Jim Walmsley! We met Jim way back in 2016, and since then, we have been two of his biggest fans. Reconnecting more than 7 years later after his course record triumph at UTMB was such a joy.

Jim opened up about everything around UTMB, from his specific training approach to the emotional side of getting vulnerable, "failure," and finally achieving his big goal. Jim moved to France with his partner Jess, with everything pointed at this one event. How do you respond to adversity when so much is on the line in a very public way? He stepped into the fire with vulnerability and courage, and there are tons of lessons for anything you care about in life.

Topics: the emotional side of achieving his goal, overcoming low points and failures, pressure, training volume, his approach to workouts, going dark on Strava before UTMB, how his training has changed over time, nutrition during and after runs, his next big scary goal, and his legacy in the sport.

We can't wait for you to hear this one! We love you all! HUZZAH!

We brought joy and so many spike proteins to this episode! The main training topic was on post-UTMB reflections about lower volume, higher energy training from the incredible Leah Yingling. You don't need to hammer your body to have success! We discuss why endurance training should uplift feeling good as a proxy for adaptation over time, starting at the cellular level and going all the way up to brain function. Healthy athletes crush b*tches!

A background theme of the episode was the sickness going around our house, and what it looks like to BELIEVE when dealing with tough moments. Though maybe we should have believed in booking refundable plane flights to the Grindstone 100k.

And there were tons of other fun discussions! Topics: acute versus chronic stress, volume accumulation, ultras and health, how our inner children might be guiding some of our athletic journey, the most uplifting story from a listener about their mile race, why Deion Sanders is our favorite coach, Coco Gauff's swag, Barry Bonds' Strava profile, heart rate changes across a season, interval duration, and hot takes.

This very special episode is coming to you from Chamonix, right after the finish of the UTMB races! We were all around the courses, screaming until our voices gave out, gathering up all the inspiration from the incredible athletes. Our goal is to transport you to France with us for the most historic year ever! For the optimal listening experience, consume this podcast with a warm baguette.

The main stories were Courtney Dauwalter and Jim Walmsley at UTMB. Courtney redefined what is humanly possible this summer, and we discuss whether she is the best athlete ever across sports. Jim went all-in for his victory, moving to France to train on these trails. That course record is the payoff after years of hard work and belief. We are living in a moment of running history that will be talked about 100 years from now, and part of that future discussion will revolve around this year's race. How cool is it to be living history in real time?!

And there were so many other awe-inspiring things to talk about! Topics: Zach Miller's ability to dig deep, the importance of confidence, the power of being a hype squad, our European experience, France hot takes, training thoughts, why we are attending the CHURCH OF THE BIG QUADS, how age may not be the limiter that some previously thought, the benefit of cross training, and so much more.

We are extremely sleep-deprived, but more full of life than we have ever been before. The highs and lows of UTMB are metaphors for life, and this episode aims to bring you a steaming baguette of existence. We love you all! HUZZAH!

We traveled halfway around the world to bring you this very special episode from Chamonix, France, the site of the UTMB races later this week! Our sleep is low, but our spirits are high. The main topic was on initial reflections on European racing and UTMB later this week. Our biggest prediction is that North American runners are going to have some major success over here in the coming decade, and we explain why. It's not just because we are extremely biased, though that plays a role. That discussion built into a new study on "physiological resilience" and how there may be a new pillar of training theory. For those scoring at home, that means there are now 4 pillars in the literature. Bonus pillar?! Huzzah!

That's not all! We chatted away the jet lag for one of our longest and most fun episodes ever. Other topics: the ubiquity of adversity, our deep thoughts on Europe, a wild new study on ultra endurance events and cognition, the evolutionary implications of the study, some breakthrough research on heat exposure and hemoglobin mass, hot takes, and an incredible listener corner.

From that listener corner: "The race showed me that strength didn’t come from doing the things I can already do, but trying the things I didn’t think I could."

We had a blast on this episode talking about some of our favorite topics! The main discussion was on takeaways from a magical Leadville 100 Miler. Jacquie Mannhard's breakthrough win came from shockingly low training volume (often under 45 miles per week) and we break down some lessons from her journey. At the finish, she popped a champagne bottle like it was her destiny! New life goal: train hard to pop them bottles. We also break down this year's UTMB races, making some predictions and debating some big themes in the growth of the sport. Is this the year that Jim Walmsley wins? Yes, one of us thinks. Will we bet against Courtney Dauwalter? At least one of us is not stupid.

And that was only the start! Topics: a new study on energy constraints and compensation, some relationship thoughts, a listener corner that will give you so much life, and hot takes. Here's one take we are comfortable writing down: standing desks are how we know the Devil is a furniture designer.

This episode was a total joy talking about food, brains, and training! The main discussion was on a term sent in by a listener: "food doping." Endurance sports are being revolutionized by a focus on high fueling levels during activity. Some cyclists consume up to 600 calories per hour in hard races! In the process, performances and fatigue resistance are accelerating at rates that haven't been seen since previous eras defined by PEDs and cheating. Is mid-activity fueling the secret to unlocking your potential in a healthy and sustainable way? We talk about the science and practice from the cutting edge of endurance performance. Your slurps will set you free!

We also geeked out on a survey of coaches discussing individual response rates in research, and how mental health is often viewed as a confounding variable. In the survey, coaches thought that actual physical training was 5th in the list of most important elements in determining adaptation. Meanwhile, research rarely focuses on all of the non-physical variables that go into individual responses! We discuss the offset, teeing up some exciting opportunities for athletes and coaches.

And that was just the start! Other topics: big training blocks, coaching science, gut training, sports stories, masculinity and gender, toenails, and hot takes.

We zoom out to talk about multi-year growth, a study on speed and ultra performance, and the balance between long-term health and short-term performance. Health and ultra performance can go together like ketchup and everything! We also talked about how we apply the principles of double threshold workouts using uphill treadmills and cross training. Yes-way to Norway!

And this episode was jam-packed with some of our favorite discussions! Topics: our all-time favorite study on aging and performance, Olympic Trials thoughts after the announcement of a noon start time in Orlando, the Kauai 50 Miler and the inspiring boss Ryan Miller, a tutorial from Megan on the side-pee, a study on timing strength training for optimal adaptations, and hot takes.

The theme of this episode: we are all powerful dump trucks! The main training discussion was on a new study looking at how strength work may help (or hurt) mitochondria adaptations. This study had wildly unexpected results, just like we like them! We also talked about our experience with sweat testing and some of the research on hyperhydration. We expect the science of hydration (personalized based on genetics) to be a frontier of performance and health in the future. And the future is tasty.

Plus we had so much joy talking about a whole host of topics! Roadmap: Courtney Dauwalter's plan to race UTMB after setting course records at the Western States 100 and Hardrock 100, Megan's breakthroughs in side-short pee science (Nobel Prize?), our theories for why times for longer distances are progressing more than the 800 meters on the track, a study on morning versus afternoon training, some of our favorite storylines from the Tour de France Femmes, listener questions on dealing with injuries and RED-S concerns, 2 incredible listener corner emails, and hot takes.

We came into this episode with so much excitement to talk about some of our favorite topics! This week's main discussion was on a new study examining the cellular-level effects of chronic stress. We zoom out from the biology of stress to talk about what it may mean for training. If you play your cards right, maybe rest days will make you live forever! We also had a joyous time talking about the future of artificial intelligence and athletics, through the lens of coaching, before zooming out to everything. This is an area where we aren't experts, but we have some OPINIONS. Long story short: we think that AI is going to transform most fields, including our work. Even as we strive to understand what the future might look like, we think it's a hopeful message to embrace what makes you human!

And that was just the start of the fun topics! Here's just a smattering of what we talked about: reflections from the aquarium, filter water bottles for hydration, the best ankle tape, a study on social media and performance, a new 8k record with a big asterisk, Taylor Swift's fatigue resistance, the restaurant that will change your life, final reflections from the Tour de France, what it means to "love" running (or anything), sweat rates, and Hot Takes. There are apparently people out there who listen to classical music for their workouts. We disagree with that approach, and suggest classic Ludacris and Blink-182.

We brought hearts full of love and legs full of toxic waste to this episode! Our main discussion was a big breakdown of science-driven lessons that we try to put into practice with racing. Megan is BACK, winning and crashing the overall podium at a tough mountain 25k! We talk about the science of pre-race carb intake, and how we screwed it up. Pro tip: make sure your pasta is not made of beans. Other topics: pre-cooling and performance, hiking v. running, altitude considerations, ankle taping, using rest opportunities, and liquid fueling.

The most fun we had though was talking about Courtney Dauwalter making history at the Hardrock 100! Three weeks ago, she demolished the record at the Western States 100, only to back it up with another record at Hardrock. How is that possible? We speculate on the physiology behind the best ultra athlete in human history, and what we can all learn from the GOAT. Ice cream is necessary, but it's not sufficient.

And we talked about so many other fun things! Topics: blood volume and performance, what that means for hydration and altitude, the murky science of fatigue resistance, more science from the Tour de France, a wild story about Strava being used in war, Hot Takes, and the most life-affirming listener corner.

This episode was one of our favorites ever! The main discussion was on stories from the US Track Championships, and lessons that can apply to all athletes. Even if you don't follow track, we think you'll come away from this discussion ready to shoot the scariest shots. Believe! We also talked about some of the science of the Tour de France, where training and fueling theories are put to the test at the limits of human performance. We can learn a lot at the edge. And at this edge, one thing we learn: eat all the carbs. Carbs make champions, it's science!

And we had tons of other fun discussions! Topics: iron levels, altitude acclimation, a debate about junk miles, running uphill, focused speed development, a wild new study on evolution (and how that might apply to athletics), a study on fatigue resistance in women, body image, and hot takes.

We put on our party super-shoes on for this joyful episode! The main discussion was on a new study on the evolution of world-class endurance training. We dig into researcher predictions before providing a bunch of predictions of our own. How will new tools and wearables change the game? What about artificial intelligence? Can AI do what we do as coaches? It probably can. As soon as AI learns to give affirmations of love and belief, we are screwed. The future is going to be so full of excitement, and we can't wait to share our thoughts with you!

Other topics: the benefits of dreaming while you're awake, our big dreams, supersized mid-run fueling strategies for adaptation and performance, Western States follow-ups, the power of working together in races, thoughts on how to use supershoes, running with poles, body acceptance, and hot takes.

WOW, we just witnessed a Western States 100 that may change how ultras are run forever! We recorded this episode right after spending all day and night coaching and cheering at the race, so our voices are wavering, but our excitement is UNSTOPPABLE. We couldn't wait to tell you everything about the event, focusing on stories and lessons that will be helpful even if you don't race ultras.

The big story was Courtney Dauwalter's legendary course record performance, taking 75 minutes off the previous best. We discuss whether it was the best performance in endurance history (yes), and whether we will ever doubt Courtney in the future (no). She gave a tailwind to the entire women's field, in a group of performances that we think may change how ultras are run in the future. The edge may be farther away than we think, and that has some incredibly exciting implications for what we know about human endurance!

And that was just part of the joy of the day! Other topics: fueling lessons, pacing, endurance science, coaching at the race, training takeaways, tradeoffs between the brain and the body, lots of studies, and so much more. This race was a small step for a Courtney, but one giant leap for Courtneykind!

We had a party on this episode with so many fun topics! Training discussions were mixed in throughout, like chocolate chips in a BIG cookie. That included how to mix intensity-controlled intervals with harder VO2 work, uphill running form (lean forward!), the importance of threshold and critical speed in all events, and what happens when your private parts go lactic. Things got a bit wild!

But our favorite segments involved the Western States 100 and Broken Arrow Skyraces! The Western States breakdown started with a podcast-exclusive statistics analysis of the best performances ever. The data took us through an adventure into advanced statistics in other sports, how they change those games, and how stats could change running. We finished with stories and predictions! We think the course record is going down, and we'll tell you why. Plus, we had fun recapping lessons from Broken Arrow that could apply to all athletes.

And there was so much more joy! Other topics: Megan's PhD graduation, humor as a defense mechanism, the head versus the heart in running and life, improving climbing, and an important new study on low energy availability. Just wait until you hear about these study findings. Keep that fire burning sooooo hot!

We brought a heaping helping of excitement to this episode to celebrate the most wonderful time of the running year! The main discussion was on the 2023 World Championships for trail and ultra-running. We break down the storylines, including an analysis of race tactics and training for WORLD CHAMPION Grayson Murphy. The courses were absolutely wild, and there are lessons for all athletes. Some of those lessons are about training and racing, and some are about not trying to cool yourself off with bottled sparkling water. Though it does sound quite refreshing!

The main training topic was on training for shorter events, and how those principles apply to optimizing potential at every distance from the mile to 100 miles. The fastest runners in the world use intensity-controlled principles even when they are racing very short distances. We zoom out from examples on the track to talk about how the same principles are at play in longer distances. Physiology is SO COOL! Except GI tract physiology. It knows what it did.

And that was just the start of the fun! Other topics: getting hyped for the Western States 100, an incredible story about coaching and love, how to improve uphill running, whether intervals should be steep, the tradeoff between aerobic and mechanical adaptations, 9 hot takes from listeners, 3 world records from the track, track super-spikes, and a listener corner about shooting your shot.

You'll never guess what a listener said about squirrels in the Hot Takes segment. We love our listeners and their weird takes!

This episode was the most fun ever, perfect timing for the 3-YEAR PODCAST ANNIVERSARY! The main training topic was on what it means to dream big, and why it matters for physiology as much as it does for the brain. Our exploration of the dream-big topic navigated through our own journeys (including our plans with the podcast), the science of coaching, and how small nudges can fundamentally change our long-term trajectories. We also geeked out on some fascinating scientific takeaways from the ACSM Conference, including calorie counting (and why we are against it), psychological factors of performance and coaching, and fueling and Boston Marathon results. Our car was stolen at the conference, but it was worth it for the sexy science. One Subaru in exchange for 30 minutes of podcast material and a few jokes? DEAL.

And our fun really boiled over on the rest of the episode! Other topics: lessons from 3 years of the podcast, a Molly Shannon book excerpt that will blow your mind, why we are so inspired by the people who took our car, a listener question about calibrating energy intake, how people pleasing may affect injury rates, a study on the placebo effect in mentorship, timing your iron intake (and how iron may interact with mental health), a review of recent menstrual cycle studies, and HOT TAKES. These takes are too hot for TV.

We hope you enjoy this celebration as much as we did, and half as much as one of our listeners enjoys their cat (it'll make sense after Hot Takes).

We filled our wine glasses with protein powder for our favorite day of the week: PODCAST TUESDAY! The main training topic was on how athletes can think about strength work. It's an area where our coaching approach has evolved over time based on how we have seen the research interact with real-world performance! Should you use lighter weight or heavier weight? One set or multiple sets? Should you be grunting like you're passing a kidney stone the size of a pineapple? We break down the magic exercises, highlighting studies that show rapid adaptations for health and performance. Strength work can even be fun! Yeah, we said it. FUN. Like if the DMV hosted a dance party!

Maybe the strength work is giving us better endurance, because we talked about so many fun things on this episode! Other topics: realizations about work, why having a bike can be helpful for all athletes, a massive ultrarunning project from Lululemon, cool science on brain function in habit formation, our favorite fuel and hydration company (BAGs for life), our thoughts on the new Golden Ticket races that were just announced, and HOT TAKES. Our listeners have some spicy thoughts! It's going to take 12 wine-glass protein shakes to wash out this spice.

We woke up before sunrise like it was Christmas morning for our favorite day of the week: PODCAST TUESDAY! The main training topic was on simple tips to improve technical running, and how the principles of thinking about form on difficult terrain can also improve health and performance on roads. After this episode, you'll believe in the ultimate power of THE CHOP. We also talked about a wonderful new study (led by Dr. Megan) with a whopping 10-year time horizon, looking at improving health outcomes in collegiate athletes. The conclusions have profound implications for how we think about athletics, performance, and culture!

And that was just the start of the fun! Other topics: hormones and athletics through the lens of a listener question about how training impacts their sex drive, the science of collagen, the perils of professional running (that may apply to whatever your profession is too), the debut of the long-awaited Ultra Legs strength routine, and MORE HOT TAKES. You'll hear about someone out there with a truly bonkers approach to preventing blisters. We can't wait for you to find out and share our horrified admiration.

It's getting hot in here, so we took off most of our clothes for PODCAST TUESDAY! The main training topic was on a new review study looking at all of the research on long-term training approaches. What works? What doesn't? On a scale of 0 to infinity, how much ice cream should you be eating? We have 3 takeaways for all levels of athletes about training volume, deemphasizing VO2 max, and cross training. Ice cream is implied! We use that study as a jumping-off point to discuss how our training methodology has changed over time, focusing on how we have evolved on workout structure, speed, hill strides v. flat strides, and aerobic blocks.

And that was just an appetizer for our favorite new segment: HOT TAKES. Listeners sent in 12 of their hottest takes about running and life, which we reacted to. You'll laugh. You'll learn something. You'll be mortified at how wrong some people are (including us). Be ready for wisdom and whimsy!

Other topics: shoes we recommend, a discussion about protein intake, protein powder reviews, race photos, and body image as an athlete. This one was so much fun!

We are so excited for this episode where we got to party with one of our favorite people: Grayson Murphy. She was fresh off a double national championship, winning the U.S. Uphill Champs on one day, followed by the U.S. Mountain Champs the next day, both in dominant fashion. In a few short years, she has established herself as one of the best trail runners in world history. How did she do it? Grayson describes a journey that was as much emotional as physical, learning to find happiness in the long-term process. Her incredible story features going to college to play soccer before finding out she was quite good at this running thing, becoming a professional and learning that she needed to follow a different path, and then courageously blazing her own trail in the sport. Her race wins are cool, but what's so inspiring about Grayson is her independent spirit, and how she has discovered that she gets to decide what it means to be successful in athletics.

And that was just the start! Grayson talks about everything from overcoming competition anxiety to dealing with injuries to her fueling secret (dino nuggets sponsorship please). We hope this episode leaves you with inspiration to take the trail that's most meaningful to you. Especially if that trail is a bit overgrown and scary!

We did a happy dance for the most wonderful day of the week: Podcast Tuesday! The main discussion was on fun takeaways from racing the Canyons 100k. David stepped up into the unknown and was 5th place! But what made the day really special was hitting a low point when it seemed impossible, and finding out that there was more to give. Our suggestion is to try something really big and really scary, whether it's in athletics or something else. Shoot those shots! The race discussion led to tons of fascinating topics: the science of "deception" in hot conditions, drug testing, the role of ego, the power of subconscious expectations, inspiration from people pushing their limits, and so much more! We also discuss the wildly uncertain area of electrolyte consumption, and how population-wide recommendations may not apply to individual athletes. This race was the most fun experience OF ALL TIME, and we can't wait to do more of these. Hopefully this discussion will inspire you to try something that seems unthinkable!

And that was just the start! Other topics: the US Mountain Championships and the legend of Grayson Murphy, 5 rules for fueling runs based on duration and intensity, a shocking revelation about our favorite grocery store, last week's news of a positive drug test from an elite triathlete, and a question from a listener on how to optimize fitness at lower training volumes.

Our only concern is that the happy dances on this episode may lead to cheek cramping (faces and butts). Keep the salt pills close by.

We put our party hats on for the ultimate celebration: Podcast Tuesday! The main training topic was on lactate shuttles in the body, and the connection between lactate and fatigue at all intensity levels. It's so fascinating how this molecule connects what we all feel during training, from a professional athlete to someone who is going on their first hike! But the main discussion was on Megan's PhD defense and her research in female athlete health and performance. The study findings = IMPORTANT. The double doctor swag = ACTIVATED. We discuss takeaways from tackling big scary goals! The main one to remember is that wearing black prevents the pit stains from being too obvious.

And you better believe we were just ramping up! Other topics: rapid protocols for heat adaptation and how that may impact performance in all conditions, a new study that connects blood volume to short-term fitness changes, emotional state and performance, our thoughts on a big scandal in ultra running, adaptation to downhill running, dopamine and perceived exertion, the interaction of running and cross training, and a follow-up on training the stomach for people with really bad stomachs. Your farts are not your destiny!

We had such a great time with this one. May your races be cool and your fitness be hot!

We turned our happiness meters to 100 for our favorite day: Podcast Tuesday! The main training topic was on the science of gut training. The stomach needs to be trained in a methodical way just like the aerobic system, but people rarely talk about how much this part of training theory plays a role in endurance. We discuss the mechanisms, studies, and considerations, ending with 4 tips to improve your performance and health. Your gut is beautifully unique and important! No matter what the pre-race porta potty says! We also did instant reactions to the Boston Marathon, including hot takes on Kipchoge's surprising fade, the wins from Chebet and Obiri, and our theories for why the race played out like it did. Plus some training takeaways from the incredible performance from Emma Bates! She uploads all of her data to Strava, which is automatic HERO STATUS.

And that was just the start! Other topics: tapering for the Canyons 100k, reflections on the past and future, a story about friends and dudes, a discussion about the awesomeness of hiking, a breakdown of the science of running and longevity, and questions from listeners on dealing with fatigue and downtime.

The most exciting time of our week is here: podcast Tuesday! The main training topic was on the trend of increasing carbohydrate intake during activity, sometimes to extreme levels around 120 grams per hour (480 calories!). We review some of the science of how glycogen levels relate to fatigue processes, along with GI considerations and our own personal experiences. Is it the next frontier of fueling, or a passing fad that will cause more DNFs than breakthroughs? The jury is out, but the carbs are in. We also talked about the principles of strides: what they are, how they work, and why they can lead to astronomical progress. There is a speed beast within all of us! And that speed beast may be farting a lot from all those carbs.

Plus, we did something extra special with this episode and answered lots of listener questions! Our podcast audience is so smart, so kind, so awesome. Topics: pre-race nerves, the Lake Sonoma 50 Miler, the physiology of celebrating yourself, the Paris Roubaix bike race, on-course nutrition, cross training doubles, how to approach injuries during training, and considerations for hormonal tracking. There were tons of deep dives into the coolest concepts! And as usual, there were some extra shallow dives as well.

Remember: Overnight success stories are years in the making. Let's make those years full of celebration! And sweet dance moves! But you gotta keep the glycogen high in the hips to avoid booty cramps.

The most fun time of our week is here: podcast Tuesday! The main training topic was on Zone 2, focusing on what it is and how to find it for yourself. If you're anything like us, understanding the metabolic and aerobic physiology will explain so much about training theory, and you'll get way faster in the process. Zone 2 is like Hansel, it's so hot right now. We also talked about some nuances of iron intake, and how appropriate supplementation can CHANGE YOUR LIFE. Did we give a multivitamin containing iron to our baby Leo as a case study? Yes! Is he is ready to take on the baby Tour de France? You betcha! Get the padded baby shorts ready.

And you better believe that was just the beginning! Other topics: 3 TV show recommendations, how to encourage adaptation through fatigue, what comes after overload training, a bunch of thoughts on the Gorge trail races, why philosopher Eckhart Tolle is our favorite running coach, some thoughts on artificial intelligence (it makes a great DJ!), the importance of celebrating yourself, and so much more. The episode finishes with a beautiful listener email, so make sure you stick around for that inspiration!

As Coach Eckhart says: "On a deeper level you are already complete, and when you realize that, there is a playful, joyous energy behind what you do." Do you think he likes hill strides and pizza? We bet he does! Does he coach babies for bike races? He does now! YOU ALL COMPLETE US.

We brought a jubilant energy to this episode, countering a lack of sleep with a surplus of caffeinated gels! The main training topic was on overload training blocks, which consist consist of volume and/or intensity increases that last anywhere from a couple days to multiple weeks. We review some fascinating studies indicating that overloads may spur breakthroughs, but can also lead to disaster. How do you thread that needle? That's where the science meets art, and where things get REALLY FUN. Rules are meant to be broken! We also discussed how endurance limitations are often just fueling limitations, and why experimenting with higher carbohydrate intakes during activity could change how you think about your physiology. Carbs make champions!

And that was just the start of the excitement! Other topics: a new study on caffeine and health, the relationship between running cadence and endurance, the importance of inclusion, how to think about cross-training, the 48-hour world record, bloodwork and the relation with intensity distribution, why you need to dial in your Zone 2 effort, a question on shoe cushioning for long races, a book recommendation, and much more!

We also discuss the very real, very scientific evidence for why we are entering the GREATEST TIMELINE in the multiverse. It involves kung fu... and something else we probably shouldn't type in an episode description. You'll see, and we think you'll agree.

This episode was full of Spring joy! The main training topic was on 4 key principles as athletes transition from winter training, which apply anytime an athlete is pursuing peak performance. The primary physiological discussions: how increased climbing affects adaptation and fatigue, heat acclimation and fitness benefits, sustainable strength work, and dialing into effort instead of metrics. Lots of fun studies in that discussion, plus plenty of semi-related digressions. You know, the usual! We also broke down the 2023 Barkley Marathons, one of the most bonkers races on the planet! It was a remarkable year, and the takeaways can apply to everyone.

And there was so much more fun! Other topics: Kara Goucher's incredible book "The Longest Race," the power of unplanned rest days, balancing rest with putting in the work, shoe reviews from podcast hosts who barely understand shoes, Vitamin D intake, wrong turn calculus, a new study on hopping (we're skeptical), and dealing with trauma and grief. This week's Listener Corner is so touchingly beautiful, and we hope it feels like a warm hug in a complex world.

It was such a joy to talk to one of our heroes, Joe Gray! Over his legendary career, Joe has won 22 US National Championships across mountain running, trail running, and cross country. Plus 9 WORLD CHAMPIONSHIPS! He is one of the best mountain runners of all time, with a legacy of sustained dominance that might never be matched. We have gotten to know Joe over the years at races, and he always takes his time to uplift young athletes, including us when we started out. He is an inspiration on and off the trails! 

We talked about what drives him after all of these years and his thoughts about the future of the sport. Joe also talked about the challenges of being a Black athlete in America, starting with a terrible experience when he was a young runner, and how racism affected his journey as a professional athlete. Now, he mentors Black athletes on and off the trails. We discuss how things have changed, and the problems that remain.

You may also learn a thing or two about his favorite food, Oreos. He said he "only" likes 7 of the varieties of Oreos, which implies there are more varieties than 7. We learn something new every day!

Joe is a running and life BEAST, and we can't wait for you to hear his story!

This episode got down and dirty with the most fun topics! The main training topic was on a new narrative review study describing the evolution of training theory, and why different approaches have converged on the benefits of lower-intensity training with relatively high doses of moderate threshold running, plus VO2-style speed in small doses. Figure 3 from that study is our love language, and we can't wait to tell you about it! We next discuss the implications of that approach for athletes who run uphills in training, which could change intensity distributions and present a MASSIVE opportunity for fitness improvements. Hills pay the bills. That's a STONE COLD SCIENCE FACT, and we explain how to use the principles in less structured training.

And we were just getting started! Other topics, in loose chronological order: follow-ups on relationships and jealousy, reviewing our microbiome testing experience, a wrist-based heart rate discussion, the hydration/fueling option that is BLOWING OUR MINDS, Megan's trip to a sports performance conference, studies on supershoes, a cool analysis of how perception of "talent" changes outcomes independent of actual genetics, and a new study on artificial sweetners. That last topic is Megan's opportunity to roast the heck out of David and his love of gum. 

Plus lots more! The vibes are strong in this one. We love you all!

We had SO MUCH FUN talking to Lauren Fleshman! Her book "Good For A Girl" just debuted as a New York Times Bestseller, and we think it's one of the best books ever written. The book is part-memoir, part-manifesto, fearlessly confronting cultural problems in running and beyond, while also being a beautiful and funny reflection on her life journey. In this interview, we talked about how we can change the incentive structures in athletics to put health (and longer-term performance) at the forefront. Topics included youth sports, college and professional coaching, fueling and body image, jealousy and comparison, and so much more!

Then we left the pages of the book to talk about her personal journey with mental health and identity. We simultaneously had life-affirming chills run down our spines as Lauren described how she has explored her true self, and how athletics and fueling played a role in that process. 

Lauren is a superstar. We think you'll finish this interview feeling inspired to step up to the start line of something big and scary. LET'S DO THIS!

This week's episode is jam-packed with happiness and fun! The main training topic was on 2 workouts that could have outsized benefits for lactate clearance and performance at every distance. The first workout is SO HOT right now: double thresholds, popularized by Norwegian training systems. The second is not quite as hot, but no less fun: post-interval moderate running. These sessions are on the cutting-edge of training theory, mixing a little bit of science with a solid serving of magic! We also talked about the importance of understanding your blood work. Yes, David finally got a blood test, and he deserves at least 3 to 5 lollipops. The results were fascinating and weird, demonstrating why it's so key to take a peek under the hood to understand your physiology. 

And that's just the start! Other topics: the Black Canyon 100k and shooting your shots, the universal relevance of heat adaptation and hydration, informed supplementation, mental health and loving your ghosts, a business case study on Strava's handling of a recent crisis, a follow-up to the relationship episode, and much more. We also talked about our new favorite book "Good For A Girl," and how it can transform your approach to athletics. Like Lauren Fleshman, let's value GUTS more than the win.

This week's VERY SPECIAL episode was a pure celebration! We didn't want to stop recording, so there are a few more minutes of fun. The main training topic was an exploration of why athletes are getting faster at every distance. Our theories involve converging training approaches, feedback processes from shoe technology, and an emphasis on adequate fueling. What does the future hold? It's incredibly exciting! We also talked about practical recommendations for eating before running, starting in the science and extending to what athletes actually do in practice. Get your oatmeal packets ready. Plus we review a new study on running economy and performance, along with the training implications!

But what makes this episode so special is the final 35 minutes, where we answer questions on relationships and love from podcast listeners! The questions touch on everything from intimacy to break-ups. We are not experts, but we think it'll be so much fun. Prepare yourselves for some sound effects too!

We had such a life-affirming interview with one of our all-time heroes, Kara Goucher! Kara became famous as one of the best runners in the world, winning 3 national championships in college, a silver medal in the 10k at the World Championships, and making 2 Olympic teams. But the running accolades are just the start of her journey. Kara embraces the whole community, persevering through her own adversity to uplift and inspire others. She co-hosts the "Nobody Asked Us" podcast with Des Linden, which debuted as the most successful running podcast on the planet. She does live announcing for distance running on ESPN and NBC. And in March, her book "The Longest Race" is coming out, and it's already getting rave reviews!

On the episode, she describes her journey from being a kid in Minnesota to an international superstar. Our admiration for her is not about the running achievements. It's about all of the moments during that journey when she faced adversity, felt the emotions, and came back swinging! Kara proved doubters wrong (including the doubter in her own head). She courageously spoke her truth and confronted abusive practices at the Nike Oregon Project. And now, she's telling her story to model vulnerability and strength for everyone else that might have doubts in their own lives. 

We absolutely love Kara, and we can't wait for you to hear this interview!

This week's episode was such a fun romp! The main training topic involved the often-overlooked variable of hemoglobin mass, and how optimizing hemoglobin levels for your individual genetics could help you bring out your inner aerobic monster. Important considerations: training intensity/stress, nutrition, iron intake, and oxygen stress like altitude... plus some wild new science on how year-round heat exposure may help. We also had a follow-up based on listener questions about how we like athletes to use heart rate data from their watches. Simple calculations to figure out your Zone 2 can help make running more productive and MORE FUN! Other topics: bands-core-massage replacing gym-tan-laundry, an update on Leo's health journey, setting little goals and how athletics can help, our framework for evaluating running shoes, ways to think about adding cross training, and the etiquette of going to the bathroom during races. 

We also read the most touching and soul-affirming listener message. We love you all so much!

We had the most fun and inspiring interview with one of our best friends in the whole world, Amelia Boone! Amelia is a world-class athlete with 4 world championships in obstacle course racing, a recent win at the Spartan Trail 100k World Championships, and numerous other accomplishments. Those accolades led to magazine covers and a public profile at times when she was working through an internal journey that couldn't be portrayed in glossy photoshoots. So what did Amelia do? She opened up, she got vulnerable, and she learned to love herself independent of her achievements.

Amelia is defined by courage. She talked to us about her treatment journey for an eating disorder, why she advocates for others fighting unseen battles, the importance of complete honesty, making athletics fun, and balancing that independence from external validation with a competitive (and fun) desire to CRUSH SOULS. Do you want to start 2023 with some HOT FLAMING INSPIRATION? Then this is the interview for you.

We had a fantastic, life-changing interview with one of our heroes, Alex Honnold! You probably know Alex from the movie Free Solo, which documented his climb of El Capitan in Yosemite, possibly the most historic athletic achievement ever. But did you know that Alex is also a runner, recently completing a 50k, with plans for more? It was SO FREAKING FUN to pick his brain on climbing and running training. We asked some smart questions and some dumb ones, as is our nature.

But the training discussion was just the beginning! Alex also talked to us about avoiding the pitfalls of external validation, his advice to aspiring young athletes, the reality of aging as an athlete, parenting, fueling, and SO MUCH MORE. And get a load of this: After an hour, he turned the tables on us and asked questions about running training. His curiosity was inspiring as heck, and we all flew our freak flags together.

Alex is not just a legendary athlete, he is a stellar human whose kindness and humor lifts up everyone around him. We loved this interview, and we can't wait for you to listen! We appreciate you all so much. WOOHOO!

This episode had it all, with some of the most fun training and life topics! We kicked it off with a training discussion that could improve your form and strength FOREVER... and it involves barefoot running. We are not ashamed to speak our barefoot running truth! The main training discussion is on a new study looking at 16,518 race results to determine whether uphill or downhill splits are the most important for race performance. The results may shock you! Other topics: 5 pieces of running news (including doping and race lotteries), novel approaches to tapers, podcast stats, flopping in soccer, breakthroughs in artificial intelligence and what that means for authenticity, and much more! 

We also talk about the performance-enhancing properties of country music. Yes, we officially reversed our position on country-pop playlists! We apologize for our past errors. You only hate the ones you secretly love.

This episode was a total treat, getting to talk about some of the best topics! We started with the ONE FORM TIP THAT WILL CHANGE YOUR LIFE... maybe. It involves your glutes, so that has to be good. The main discussion is on 5 takeaways from World Champ Adam Peterman's training that can apply to all athletes, including how to balance intensity and using cross training strategically. Other topics: rejecting cynicism, a cellular-level explanation for why strides work, how the principles may apply across sports, using the bike and elliptical for breakthroughs, some cool data on iron bisglycinate, and much more! 

Most importantly, we finish the podcast with a primer on WOLF SCIENCE from a recent study showing how a parasite affects animal behavior. This episode is some wild fun! And after the wolf talk, you may find yourself setting out and becoming the leader of your pack (especially if you grew up with cats... it'll make more sense after you listen).
