Fully revised and updated for 2023, this is the inspiring journey of Dean Karnazes, an internationally recognized endurance athlete who has pushed his body and mind to inconceivable limits. Includes a new epilogue detailing his training and diet tips.

'[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.
