    We put our hands down our pants (for warmth) before this amazing episode! The main topic revolved around the Black Canyon 100k, where Jenn Lichter and Hans Troyer set course records, and the ultrarunning took another major leap forward. We discuss what we learned before laying out an overview of our ultra training philosophy.

    The sport is changing so fast that we’re almost certainly wrong (and biased) in some places. But it’s so fun to learn at the edges, and to see how that might apply to any athlete trying to see what’s possible! We finish it off by looking for lessons that we can learn for shorter distance training theory. Hint: it’s mostly carbs.

    And this one was full of great topics! Other topics: eating “real food” in workouts, Megan unleashing the speed on the treadmill, David’s foot progress, Nomio back in stock, the debate on pacers in ultras, a wildly cool study on neurons and endurance adaptation, a weird cycling study that tricked participants with financial incentives, Tadej Pogacar accidentally (?) publishing his power numbers, and a question on metabolic processes and body image.

    We love you all! HUZZAH!
