Phil Batterson is a competitive runner, former running coach, and the founder of Critical Oxygen. Phil has a PhD in human bioenergetics and a love for all sorts of endurance sports, from rowing to track and field and ultras. His goal with Critical Oxygen is to teach athletes and coaches how to optimize their physiology to maximize endurance performance. This episode is important and is a repost of episode 330 from 2023. Phil breaks down some of the complex physiology behind the three different thresholds to make it more accessible, as well as providing practical ways to apply it in training. Some of our discussion includes: Phil's journey into endurance training and exercise science What physiology defines each of the three thresholds How runners can determine their own thresholds The importance of lactate threshold work for race preparation Common mistakes when using training zones How to integrate VO2 max work with cross training Whether you like to geek out on physiology or just want to race faster, you'll learn a lot from my conversation with Phil!
