Alex Hutchinson is the author of a must-read book for triathletes called Endure: Mind, Body, and the Curiously Elastic Limits of Human Performance.  A Physicist turned journalist turned author (and a pretty good runner himself), Alex joins us on the podcast to talk about his findings in the book, what surprised him during his 10 years of researching and writing the book, and what all endurance athletes (particularly triathletes) need to know.
