296. How To Use Electrolytes, Zone 2 Problems, Strange VO2 Max Measures, The Weird World of Probiotics, and AI Training Thoughts!
Tue Feb 03 2026
We cornered the market on mozzarella sticks before this awesome episode! The main topic involved our recommendations for electrolyte use in races and hard training. Sweat replacement is one of the strangest, least understood parts of athletic physiology. We give our guidelines from lots of real-world experimentation.
And this one was full of incredible topics! Other topics: the happiest place on Earth, Megan’s first video filming and the year of vulnerability, David’s return to run, a new probiotic study showing the weird connection between the gut and brain, Kristian Blummenfelt measuring with the highest VO2 max ever (or did he?), Airpod 3 heart rate, gambling in running, Truett Hanes’ OTQ chase, our updated thoughts on applying AI in training, a Nomio follow-up, the perils of setting Z2 in the wrong place, changing directions on the track, elliptical v. bike training, bike cadence, a deep question on parenting, and lots more!
Whenever you’re in doubt about our place in the Universe, look up at the night sky, take a deep breath, and give the universal signal: SUCK IT.
That will make a bit more sense soon (maybe). We love you all! HUZZAH!
-David and Megan
