We bowed down to the power of hot mugwort before this amazing episode! The main topic was on a study that may be the long-lost "missing link" in our training theory. It took 12 elite endurance runners and had them do sprints of 100 meters and 400 meters, along with a VO2 max test. Their findings (and one striking non-finding) may connect studies on speed interventions with real-world implications. We also answered listener questions in the "no secrets" style! The most hairy question was on a topic

We collected some wonderful questions before this great episode! It's our classic "no secrets" style, where we take you behind the scenes to combine research and theory with what athletes are actually doing, but maybe not talking about. We started with a new study on maintaining heat acclimation, which helps answer questions on how to improve blood volume year-round in a sustainable way. Then it was onto the questions! Topics of the questions: sodium bicarbonate and ketone use, the difference

We got our Rich Roll on before this amazing episode! David's appearance on the Rich Roll Podcast came out this week, and we started with some takeaways from a surreal experience. We then pivot into some talk on protein in adaptation and recovery. When in doubt, the answer for us is often to throw some protein on it.Next was a truly wild study that looked at low energy availability and managed to do the impossible: it included a control group that was blinded to the intervention.

We brought some joyful and fluid-tastic vibes to this great episode! The main topic involved us picking our jaws off the floor as records were absolutely annihilated at the JFK 50 Mile, America's oldest ultramarathon. We have some inside info on how David Sinclair set the record, which we think could be Ultra Performance of the Year. Plus we worship the queen, Rachel Drake. Why are we seeing record after record get smashed at every major race? The answer likely lies at the intersection of training,

You can smell the excitement on this amazing episode! The main training topic was on David's favorite study of 2024, which caused major changes in his training approach. The study found some potential mechanisms for improved fatigue resistance, but we take it a step further into theories about solving for a puzzle that has flummoxed coaches and researchers forever. Could this study be the missing link connecting fatigue resistance and training interventions? Maybe. We dive into the cutting edge of

We celebrated huge beating genius machines before this awesome episode! The main training topic was on 10 ways our training approaches changed for Leadville and Javelina. Throughout the process of preparing for 100 miles, we made itty bitty alterations that sometimes became big shifts in how our plans usually look. We break down each of them and how they might apply to other athletes. Time to pop a squat (or 2 x 10 reps of them).Before that, we have a little love letter to listeners. That consists

We answered tons of amazing listener questions on this great episode! We approached Leadville and Javelina like science experiments, and like all good science experiments, we want to share everything before starting a new experiment for the Western States 100. This one is full of sexy science, theory, psychology, nutrition, and so much more! Our philosophy is "no secrets"... sometimes to a fault. That means spilling the beans on everything from training to nutrition to gear, plus some hot takes on

We ventured into the unknown at the Javelina 100 Mile, and we're coming back with a celebration to share! This episode is all about processing a life-changing weekend where David won Javelina in 12 hours, 45 minutes to earn a Golden Ticket to the Western States 100. There was one defining feature of the day: HEAT. Race day featured record temperatures around 100 degrees F in Phoenix, with the course traversing desert cactus that didn't offer a hint of shade.

We reached deep into the BELIEVE BAG before this great episode! It started out with all of our thoughts ahead of the Javelina 100 Miler this weekend. This journey into the unknown has it all: fears, dread, and doubt right alongside excitement, celebration, and DMX. We hope this exploration gives you a tailwind that pushes you to chase scary dreams. We also did a deep dive into a massive new meta-regression study on mitochondria and capillary development. The study gathered data from hundreds of

We put on all of our pants and jackets to record this HOT episode! The main training topic is on the wild science of heat suit training. In 2021, a case study revealed that simply wearing a couple layers while doing easy biking could rapidly expand hemoglobin mass, which could improve performance in all conditions. Numerous other studies support the findings, and now heat suits are a staple of pro cycling training. This could be a new frontier of performance! We talk about how our feelings have

We made loud grunting noises to celebrate recording this great episode! A primary training discussion was on putting the finishing touches on the quick build for the Javelina 100 Miler. It's getting very, very real. Confidence is rising, and falling, and falling some more, then rising again. We bring you into the process to feel just how hard it all can be at times for athletes of all levels. Prepare to grunt. But the main topic ventured into an area we usually avoid: heated debates.

We loaded up on some "awake" tea to feel extra caffeinated for this spicy episode! Listeners send in such great questions, and it was so fun to get down and dirty with some fascinating topics. It's called a "no secrets" Q+A because we often see conversations with elite athletes and coaches where it's clear that we aren't getting the full picture. Our goal is to be an open book (for better and for worse!).As a result, this one was full of the most fun topics! A list of some of the topics: caffeine

It kicked off with us picking our jaws up off the floor, in awe of Tara Dower's overall record on the Appalachian Trail. Coach Megan delves into what made it possible (strides and speed) and what sets Tara apart (being a superhero). This achievement will take decades to fully process! The main science talk was a new study on Kilian Jornet's physiology data from 2022 UTMB, where he won in historic fashion

We slurped down a truly inspiring amount of carbohydrates before recording this great episode! The main topic was a new study with a fascinating design, equalizing carb intake across a day, but modulating the quantity consumed in the post-exercise window. There were major changes in next-day performance! Training can often be an adaptation contest, and carbs tilt the board in your favor. We also talked about Vincent Bouillard's training to win UTMB. Running training is undergoing a rapid

We filled the pauses in conversation with all of our deepest confessions before recording this great episode! A main topic was how we thought about strength work and heat training in the Leadville 100 build. While David's mileage wasn't wildly high, he made some big changes in the last year that harness the power of heat to spur hematological changes, and strength to spur booty changes. We also talked about a new study connecting fasted training with increased incidence of bone injuries,

We pinched each other to make sure it wasn’t all a dream before recording this celebration episode! This one was all about processing David’s course record run at the Leadville 100 Miler. For 19 years, Matt Carpenter’s Leadville record of 15:42 has been talked about as one of the most untouchable marks in running. But a lot has happened since 2005, with advances in training, fueling, shoes, and altitude science. So even though Matt is a GOAT, we thought it was possible. Yes, it seemed like low

In the study, just a few weeks of heat training caused 3% improvements in hemoglobin mass, associated with jumps in fitness. However, the adaptations reversed to baseline rapidly.
