294. The Bicarb Revolution, Theory of Doubles, Vitamin D Supplementation, Stairmill Training, and Zone 2 Weirdness!

We loaded up on Vitamin D (and deodorant) before this fresh episode! The main topic was a new sodium bicarbonate study, tracking 40k bike time trial performance at altitude. It’s another brick in a really big scientific wall supporting the use of bicarb for performance. We zoom out to let you know why we think it’s also effective even in very long distances... and maybe at lower (cheaper) doses.

We also talked about Vitamin D supplementation, using a big review study showing that over half of athletes had inadequate levels. Hit the ADEQUATE sign!

And this one was full of great topics! Other topics: the power of taking 3 days off, an update on David’s health journey, arm band heart rate, our Nomio epiphany, shoe nerd news, a new analysis on running economy changes in different trail shoes, the Hopecore Corner with pieces of art we really like, a quick-hitter CBD study, improving bike power, the theory of doubles, a fun sports bra question, using the stairmill, heart rate zones, and whether to follow logic or the heart with race decisions.

We love you all! HUZZAH!

-David and Megan
