Courtney Dauwalter and Jim Walmsley at UTMB. Courtney redefined what is humanly possible. Jim's course record is the payoff after years of hard work. Topics covered: Zach Miller's ability to dig deep, the power of being a hype squad, training thoughts, why we attend the CHURCH OF THE BIG QUADS, the benefit of cross training, and more.

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 brought full hearts and clear nasal passages to this awesome episode! The main training topic was on the gargantuan Strava files of athletes preparing for the UTMB races. 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. All of our bodies, like all of our takes, are very, VERY HOTTT. For a weekly bonus episode (and bi-weekly newsletter), make sure you're subscribed to our Patreon. We love you all! WOOHOO!

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. During hot takes, we may have lost some friends in Florida. Just kidding! We don't have friends in Florida because they were all eaten by pythons.
