wakes up the appetite to run long distances. Dean takes us on a lifelong journey of ultramarathons, through the ups and downs, the friendships and lonely moments, and the struggles and rewards of each race. Dean writes in a direct and intimate way that keeps us reading like he runs--without stopping."--Kilian Jornet, author of Above the Clouds and world champion ultramarathoner

"A Runner's High is a powerful narrative on life, running and finding meaning through perseverance. Every runner should read this book."-- Jason Koop, Coach and bestselling author

New York Times bestselling author and ultramarathoning legend Dean 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 once ran 50 marathons, in 50 states, in 50 consecutive days.

In A Runner's High, Karnazes chronicles his extraordinary adventures leading up to his return to the Western States 100-Mile Endurance Run in his mid-fifties after first completing the race decades ago. The Western States, infamous for its rugged terrain and extreme temperatures, becomes the most demanding competition of Karnazes's life, a physical and emotional reckoning and a battle to stay true to one's purpose. Confronting his age, his career path, and his life choices, we see Karnazes as we never have before.

For Karnazes, the running experience is about the runner and the trail. It is not the sum of achievements but a story that continues to be told each day, with each step. A Runner's High is at once an endorphin-fueled adventure and a love letter to the sport from one of its most celebrated ambassadors that will leave both casual and serious runners cheering.
