'[Karnazes'] spirited memoir . . . can help mere mortals who want to push past their perceived limits or simply jump-start their sedentary lives.' - Chicago Tribune

In this updated and revised edition, Dean Karnazes has added an afterword full of lessons learned. 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 for three decades is now sharing the tips and learning's that have helped him to keep 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 uncovers how he merges the solitary, manic, self-absorbed life of hard-core 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.
