334. Running Form and Fatigue Resistance, Bombshell Doping News, Lactate Gel Experimenting, and How Sweat Rate Changes Over Time!
2026/10/26 | 1h 27 mins.We got in trouble at the gym before this great episode! The main topic was a new study tying deteriorating fatigue resistance to increased duty factor (ground contact time). Essentially, the longer the foot stays on the ground after a couple hours of work, the worse the fatigue resistance. That points toward neuromuscular interventions that could improve endurance.
And this one was full of awesome topics! Other topics: lactate gel experimentation, the major doping bust in road marathoning, menthol gels, our issues with high-carb drink mixes in ultras, how sweat rate varies across an event, a study on deception methods improving performance, steady running the day after long runs, shaving your legs, Strava etiquette, the problems with MAF training, and a big discussion of why we look to training approaches that work for pro female athletes to derive some training theory.
Welcome to the best episode! Oh, actually that’s supposed to say “vest” episode. We regret the error.
We love you all! HUZZAH!

2026/10/20 | 1h 26 mins.We had to clear our search history after this great episode! The main topic was a list of the ways we’ve been wrong in coaching. Examples: fasted training, treadmills, heart rate monitors, squats, and lots more. We use the discussion as a chance to zoom out and make jokes that had to be censored.
We also talked about a new study on eccentric muscle contractions, which found persistent adaptations for 6+ weeks after a single stimulus. WTF is going on?! There are major implications for how we think about training for all types of events.
And this one was full of fun topics! Other topics: our curse removal, elliptical training, a follow-up on the ultimate carbs study from last week, the problem of reproducibility of adaptations in exercise science, and lots more.
We love you all! Huzzah!

2026/10/13 | 1h 29 mins.The carbs were flowing for this great episode! The main topic was a new study on carb intake that answered so many open questions about fueling. And in the process, it inadvertently dunked on the low carb studies from last year! Get ready, we have a new all-time favorite study.
We also talked about the Chicago Marathon, focusing on the American athletes taking big swings at the front. We might love Vinny Mauri even more than we love that carb study.
And there were tons of more fun topics! Other topics: our new shoe of destiny, the best caffeine gels, a big discussion of advanced training and health in the high-carb era, a pair of carb studies that help explain what we’re seeing in the real world, the low volume base training plan, the Ironman World Champs finish, elliptical training, Chip Kelly and adapting coaching approaches for athlete skills, AI solving math problems, the Taco Bell 50k, Rachael Rudel's breakout season, and lots more.
We love you all! Huzzah!

2026/10/06 | 1h 28 mins.On this episode, we got extremely excited by some of the coolest training theory. So we just ran with it!
The big discussion was on the 10 lessons we have learned from coaching pro road runners. David took a trip to the US 10k Champs this weekend, where Emily Venters won, Allie Ostrander was 3rd, and Amanda Vestri was 4th. It gave us a lot of fodder to talk about what we’re seeing and hearing behind the scenes of the performance revolution.
Other topics: new standards for iron deficiency, Vinny Mauri’s wild training for the Chicago Marathon, our excitement for Emma Grace Hurley’s debut, the cycling World Championships, what we can learn from the evolution of cycling theory, and lots more.
We had so much fun nerding out on this one. Thank you all for being here!

2026/09/29 | 1h 21 mins.We had some deep thoughts on cheese before this great episode! The main topic was a new study on sodium bicarbonate, showing performance benefits in a long, intense protocol. We zoom out to talk about potential connections to mitochondria... in rats (sometimes). Our theory: bicarb is driving some of the performance changes we are seeing via long-term adaptation processes within cells.
And this one was full of awesome topics! Other topics: Megan’s deep thoughts on the uphill treadmill, the Toe Pro, bicarb pills, the new gear-shifting shoe from Adidas, a study on the brain-strength connection via “mental contraction training,” how hot water immersion and training interact, when to stop strength work before races, what Matt Carpenter would do in the modern era, whether big prize purses will cause more doping in trail running, carb needs before 5k races, fatigue resistance from life, bicarb lotions, and process v. results mindsets in racing.
The big PSA from this episode: be careful with your search history. Also, feel free to use our example for a convenient excuse. It will make more sense soon.
We love you all! Huzzah!
