The incredible true story of the author's remarkable transformation, at the age of 40, from out-of-shape average Joe into one of the world's best endurance athletes.

On the eve of his 40th birthday, Rich Roll was in bad shape. His days were filled with work, stress, and junk food, and his nights were spent on the couch, remote in hand. Taking out the trash was the closest he came to exercise, and, at 50 pounds overweight, a walk up the stairs left him winded. He decided it was time to make a change. After undergoing a diet detox, adopting a vegan lifestyle, and pushing his fitness regimen to undreamed-of heights, he was profiled by Men's Fitness as one of the world's 25 fittest men. Among Roll's many jaw-dropping athletic feats: he completed the unprecedented "Epic 5"--five back-to-back Ironman-distance triathlons on five different Hawaiian islands in under a week--an achievement many said was impossible. This is the story of that remarkable transformation, a complete physical and spiritual rejuvenation that proves that anyone can "find ultra" if they know how.
