Ultramarathoner Dean Karnazes Pens New Book Chronicling His Life

Jun 23, 2021

On The Mountain Life, best-selling author and ultramarathoning legend Dean Karnazes comes on.

Karnazes has pushed his body and mind to inconceivable limits, from running in the shoe-melting heat of Death Valley to the lung-freezing cold of the South Pole.

He’s raced and competed across the globe and even ran 50 marathons, in 50 states, in 50 consecutive days. 

In his new book, A Runner’s High: My Life in Motion, Karnazes chronicles his adventures leading up to racing in the Western States 100-Mile Endurance Run in his mid-fifties after first completing the race decades ago.

Karnazes confronts his age, career path, and life choices in what becomes the most demanding competition of his life.
