We start with an intro recap of the US Track & Field Championships, covering who won the prediction contest as well as the surprises and big winners from the weekend. Then, in the 36th minute, we bring Alex Hutchinson in studio with us in Austin to discuss his book Endure: Mind, Body, and the Curiously Elastic Limits of Human Performance as our first book in the Endorphin Book Club. We've also had Alex in episode 48 and 64. In this discussion on Endure, we get to some of the more practical elements of the book and how to make those work in your training. Plus, we press Alex on why he didn't include more direct take-aways in the book, including a few tough questions from listeners. We will announce our next book in episode 82 so stay tuned for the next book to add to your library.
