The main topic revolved around the world records at the London Marathon, including Sebastian Sawe’s 1:59:30 winning time. We discuss his mid-race fueling, bicarb use, shoes, and so much more. Plus, there was an important study measuring the differences in mechanical output between sprints, strides, and plyometrics. This study could be the missing link that identifies why strides are such a ubiquitous part of elite training approaches. And there were tons of fun topics! Other topics: the purchase David is not proud of, a game theory hypothetical, a high-carb case study, the amazing Women’s Gear Index, luxury gear, an existential question on life and training, a potential treadmill study, barefoot shoes, iron dosing theories, and lots more. Come for the carb talk, stay for the knowledge that David will occasionally have the worst takes you have ever heard. We take back every thought we head about pressing the red button.
