| 6/16/26 | 315. How Lower Carb Arguments Miss The Mark, Answering Bicarb Questions, Overload Weeks, and Heat Training! | We developed the ultimate AM wake-up hack (which we tell you about in the intro) before this great episode! A main science topic was a new paper on how the temperature in an athlete’s training location influences race performance. It tells a story about heat training generally that everyone needs to pay attention to.And guess what? A new journal article makes yet another argument against higher carb approaches. David brings big rant energy and we talk about how the scope of conclusions from exercise science can sometimes be misinterpreted. Plus, there were so many fun discussions! Other topics: Megan’s new documentary coming out on Thursday, what we’re seeing with bicarb use, overload training weeks, some cool science on Omega-3 supplementation, and questions on carbs in cycling, the backwards treadmill, big races, and more!To paraphrase our muse Jesse McCartney: we don’t want this episode to go to waste, we want you and your beautiful listens.We love you all!

| 2/10/26 | 297. Long Runs Explained, The Training Shoe We Love, Black Canyon 100k Predictions, Shockwave Therapy, and Lindsey Vonn’s Courage! | Real talk! This episode is great, but maybe don’t listen out loud IN PUBLIC. The main training topic was a deep dive on long runs. We break down some of the competing long run theories, and how they fit into performance. The discussion ends with 5 principles to know (subject to change as competing theories duel it out).And there were so many amazing topics! Other topics: the Real Talk Express, Megan’s mental approach to hard efforts, accidental caffeine, David’s bike progress, Lindsey Vonn’s incredible toughness, why Jessie Diggins is our favorite athlete, rumors of injections in sensitive places for ski jumpers, Jonas Abrahamsen finding his strong and pushing the limits in cycling, why the Adidas Evo SL is an amazing training shoe, Black Canyon 100k predictions, a weird and wild study on sexual activity, a discussion of shockwave therapy, and lots more.May your drinks have secret caffeine, and may your talk be real.

| 2/3/26 | 296. How To Use Electrolytes, Zone 2 Problems, Strange VO2 Max Measures, The Weird World of Probiotics, and AI Training Thoughts! | We cornered the market on mozzarella sticks before this awesome episode! The main topic involved our recommendations for electrolyte use in races and hard training. Sweat replacement is one of the strangest, least understood parts of athletic physiology. We give our guidelines from lots of real-world experimentation. And this one was full of incredible topics! Other topics: the happiest place on Earth, Megan’s first video filming and the year of vulnerability, David’s return to run, a new probiotic study showing the weird connection between the gut and brain, Kristian Blummenfelt measuring with the highest VO2 max ever (or did he?), Airpod 3 heart rate, gambling in running, Truett Hanes’ OTQ chase, our updated thoughts on applying AI in training, a Nomio follow-up, the perils of setting Z2 in the wrong place, changing directions on the track, elliptical v. bike training, bike cadence, a deep question on parenting, and lots more!Whenever you’re in doubt about our place in the Universe, look up at the night sky, take a deep breath, and give the universal signal: SUCK IT. That will make a bit more sense soon (maybe). We love you all!

| 1/27/26 | 295. Debunking Low Carb Science for Endurance Athletes | We ordered extra-extra cheese before this deep-dive episode. The main topic took up most of the recording today, involving a new narrative review that argues for a low-carb approach for endurance athletes.The real-world performance benefits of carbs are clear for anyone who has traveled this path, but at the end of the day, who cares? It's just performance. The low-carb believers can get left behind and that's ok by us.The reason we are talking about this relates to health. The carb conversation is nuanced--it's not about taking in as many carbs as you can all the time, and their arguments point out legitimate discussions about how to balance fueling in training and life. But their arguments also infiltrate the broader discussion of nutrition, and anyone who works in this field sees what can happen on the other side.There is a boneyard of ruined careers from serious endurance athletes who have undershot carb intake. The negative mental and physical health outcomes from carb restriction take this out of the academic realm and into much more serious places. We love carbs because we love performance. But mostly we love carbs because we love people, and we want to see athletes be able to shine their lights as brightly as possible.Other topics on this episode: our approach to cross training, the incredible Beth McKenzie episode on the Freetrail podcast, Alex Honnold free soloing a skyscraper, a study tracking DEXA scan results with stress fracture outcomes, and we answer an important question from a listener about dealing with a tough health diagnosis.This one starts with a different tone as we grieve the terrible news from Minnesota. Thank you for being on this journey with us.We love you all!

| 1/20/26 | 294. The Bicarb Revolution, Theory of Doubles, Vitamin D Supplementation, Stairmill Training, and Zone 2 Weirdness! | We loaded up on Vitamin D (and deodorant) before this fresh episode! The main topic was a new sodium bicarbonate study, tracking 40k bike time trial performance at altitude. It’s another brick in a really big scientific wall supporting the use of bicarb for performance. We zoom out to let you know why we think it’s also effective even in very long distances... and maybe at lower (cheaper) doses.We also talked about Vitamin D supplementation, using a big review study showing that over half of athletes had inadequate levels. Hit the ADEQUATE sign!And this one was full of great topics! Other topics: the power of taking 3 days off, an update on David’s health journey, arm band heart rate, our Nomio epiphany, shoe nerd news, a new analysis on running economy changes in different trail shoes, the Hopecore Corner with pieces of art we really like, a quick-hitter CBD study, improving bike power, the theory of doubles, a fun sports bra question, using the stairmill, heart rate zones, and whether to follow logic or the heart with race decisions.We love you all!

| 1/13/26 | 293. Ultra Runner of the Year Rankings, Unintentional Low Carb Studies, Health Update, Continuous Lactate Monitors, and Blood Tests! | We got our big juicy pumps for this amazing episode! We started by talking about a couple pieces of personal news, including a shockingly cool number 4 ranking in the Ultra Runner of the Year voting... and some tough health findings from an MRI. The newest shoe review is a medical boot. It’s still better than most trail shoes.The big science discussion was on a pair of studies on advanced female runners, with both finding low carbohydrate intake on training days. One of the studies on elite athletes found that 94.3% had low energy availability! We broaden out the discussion into nutritional approaches generally. And David tries to broaden it out into a thinkpiece about the food pyramid. At a certain point, maybe your thinkpiece is so wrong that you eventually loop around and become right? Don't answer that.And this one was full of great topics! Other topics: our approach to training and health with the foot, a study on using heat training to substitute for other types of training, what we’d spend with $200 a month, how we are making money off AI, the Burrito League, some quick thoughts on continuous lactate monitors, Shelby Houlihan and Molly Seidel setting records at trail races, Raya for trail and ultra runners, sleep and FKTs, blood tests and training for downhills in a flat place.We love you all!

| 1/6/26 | 292. The Countdown! Our 10 Most Important Training Studies of the Year | This was one of our all-time favorite episodes! We discussed takeaways from our 10 top endurance performance and health studies of 2025, full of science, recommendations, and debates. We don’t want to give away the countdown, but this one had everything! We’re talking fueling, training, brain health, colon health, and shoes. You just know there had to be a shoe study. Running shoes are 92% of David’s personality. Our mission was to summarize the science in a way that would help you take the research into the real world. We think that if you can stay 1-2 years ahead of widespread adoption of new scientific principles, you can always have an edge even as the world starts to catch up. Plus, it’s fun! Not as fun as a colonoscopy, but still fun!We also talked about 3 pieces of running news, including Shelby Houlihan’s first trail race, a new bicarb energy bar, and Ann Trason’s 100 mile performance.
