We pondered the genetics of smelling ants before this great episode! The main topic was a new study that found the brain may use myelin lipids for fuel during low glucose conditions like marathons. This could have massive implications for how we think about fueling and fatigue resistance, including for cognitive function. Our big theory: fueling is just as much about nourishing and protecting the brain as it is the legs.

And this one was full of amazing topics! Other topics: the resurrection of the green shorts, “tension” training via uphill biking and running, heat suit training, genetic data, why post-exercise ketones may be most beneficial after longer efforts, the wild connections between heat response and evolution, body image and clothing choices, heart rate after layoffs, racing athletes we coach, dealing with break-ups, the art of sweat testing, and our frustration with nose-breathing recommendations.

May your shorts be green and long,

-Megan and David

We took off our armor for this incredible episode! The main discussion might have been one of our most important (and fun) ever: the Big Alta 50k DNF, failure, and what it truly means to go for it. David raced Big Alta because it was somewhere that he couldn't hide. We needed to gather data about what happened at the very edge of human capabilities. And when you F around...sometimes you find out.

We hope that you feel a connection to your big scary dreams. Thank you for giving us the courage to dream bigger!

And this one was full of great topics! Other topics: racing lessons from Big Alta, why ankles are annoying, guys v. dudes, running your own race, Jim Walmsley dominates at Chianti, Kilian is going to Western States, sauna v. hot tub, going from 0 to 1 to 2 kids, running groups, bike v. treadmill, core work, life "balance" for people with big goals, long-term training builds, and lots more.

This episode gives you a raw window into the true story that athletes rarely tell. We all fail. Life really unfolds in what happens next.

We love you all! HUZZAH!

We celebrated the 250th recording for this great episode! The main topic was a new study on fatigue resistance. How do you actually improve performance after multiple hours of work? It’s the greatest mystery of endurance, and whoever solves it will have a big advantage. We think that we have some answers for training, fueling, and the nervous system.

And this episode was jam-packed with tons of amazing topics and questions! Other topics: race week reflections before the Big Alta 50k, confidence, showing up authentically for a serious episode 250 discussion, positivity and love in a complex world, fatigue resistance training, OnlyFans sponsors Sabrina Stanley, Nike sponsors Riley Brady, Outside Mag’s revolt, and more.

This one got deep and personal, like we also get with our treadmill.

Thank you so much for your support over 250 episodes. Let’s do another 250! We love you all. HUZZAH!
