    We spread our toes wider than nature intended before this great episode! A main topic was on the fueling evolution in the Tour de France, and how that has predicted everything that has happened across endurance sports. We also break down what fueling looked like in the 1990s from an old study! High carb is changing everything, and cycling is always the first mover on the next breakthrough.

    We also did an update on uphill treadmill threshold workouts. More than any training intervention we have ever seen, these workouts seem to be correlating with better performance for road runners, where every 1% counts. 

    And this one was full of fun topics! Other topics: David’s embarrassing online order, the wild and mostly unchecked world of shoe prototypes, the Hardrock 100 (featuring 50-year old Ludovic Pommeret setting another course record!), AI cheating in college and what that means for creative work, a “supplement” at the World Cup, when to move to the 100-mile distance, peeing thoughts, our uncertain take on Nomio in ultras, our heat video in the hot tub, and a big discussion of how we think about learning in coaching.

    Come for the vibes. Stay for David realizing mid-hot-take that he is a hypocrite and should stop talking about shoes.

    We love you all! HUZZAH!
