Ultramarathon Man: Confession of an All-Night Runner

Ultramarathon Man: Confessions of an All-Night Runner helped introduce the world to ultramarathoning. Now, after three decades of running ultramarathons across the globe, Dean Karnazes is still going strong. This updated and revised edition includes an afterword full of the lessons he’s picked up along the way. He gives personal details on the essential pillars of health—fitness, diet, and sleep.

What does he eat, what supplements does he take, and what kind of mattress does he sleep on? Aging well takes work, and the man who hasn’t stopped is sharing the tips and learnings that have kept him going, mile after grueling mile.

Ultramarathon Man is Karnazes’ story: the mind-boggling adventures of his nonstop treks through the shoe-melting inferno of Death Valley, the lung-freezing ferocity of the South Pole, and the awe-inspiring beauty of the towering peaks and craggy canyons of the Sierra Nevada.

With an insight and candor rarely seen in sports memoirs, he reveals how he navigates the solitary, manic, self-absorbed life of extreme ultrarunning with a full-time job, a wife, and two children, and how running has made him who he is today: a man with an ironclad body, a teenager’s energy, and a champion’s wisdom.
