In this episode, Alex tells the story of his “aha moment” during a meaningless track meet that catapulted his running career and seeded his interest in the power of the mind. He then explains the science behind VO2 max, the difference between maximum aerobic capacity and efficiency, and extracts insights from examples of extreme human performance, such as the recent attempts to break the 2-hour mark in the marathon.
