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, which we use to zoom out to discuss adaptation more generally. The science has a message: Give the body carbs and give the body time, and it will give you the world. And this one had so many of our favorite topics! Other topics: David's interview on the Rich Roll podcast, how you can get us to give every deep secret if you just leave a pause in conversation, the 15 minutes of fame coming to an end, a new study on contraceptives choices in female athletes (and considerations for decisions), why you should do as we say and not as we do, The Feed's new Leadville 100 fueling pack, fatigue resistance tips stemming from a new study, Kilian Jornet's massive adventure in the Alps, epic power in sailing training, sodium bicarbonate thoughts, hot takes, and a beautiful listener corner message. This episode is buffet of joy, humor, and questionable hot takes. Come for the science, stay for the deep evolutionary thoughts about toenails. We love you all!
