    We got intellectually swole on creatine and astrology before this great episode! The main science topic was a study connecting carb oxidation to hydration status. We explain how hydration is the gateway to fueling.

    We also provided details of the first week of David’s creatine experiment. There is some very strange heart rate data that we’re tracking. Correlation or causation? We'll find out!

    And this one was full of fun topics! Other topics: bailing on workouts on bicarb days, how runners should think about improving bike power, tons of thoughts from the Tour de France including the massive power numbers and a follow-up on overnight drug testing, AI in mathematics, a fantastic article in JAMA on tendon healing, and questions on dealing with an identity crisis in athletics, stairmill v. biking, a listener passionate about oysters, a grooming tip, Malcolm Gladwell, stoppage time in runs, and low iron levels.

    You’ll never look at Cheez-Its the same. We’re sorry and/or thank you. 

    We love you all! HUZZAH!
