We can not get enough of Alex Hutchinson’s book, Endure: Mind, Body, and the Curiously Elastic Limits of Human Performance (2018) this year. His book takes a detailed look into the science of endurance and covers heat, hydration, nutrition, and all the things that we love to think about! Alex takes us through many of the topics in his book and gives us some insight into how the brain may ultimately be the limiter on our ability to suffer, and how changing our perception of pain can expand the limits of our endurance. As an added bonus, we talk briefly with Erin Cafaro, a 2x Olympic Gold Medalist in rowing, about how she thinks about and manages pain while competing. Alex joined us via Skype from Toronto.
