For anyone who has ever thought a solely plant-based diet is not enough for successful athletes, think again. Rich Roll was your average busy American: full-time lawyer, husband, and father. On the cusp of his 40th birthday, Roll took a good look in the mirror, didnt like what he saw, and decided it was time for an overhaul. His makeover started with a seven-day juice cleanse, which then led him to what he believes is the optimal long-term diet: veganism. He also reacquainted himself with regular exercise. Two years later and 30 pounds lighter, Roll competed in the Ultraman World Chamionships, a race in which competitors swim 6.2 miles, bike 260 miles, and run a 52.4-mile double marathon. Now named by Mens Fitness as one of the 25 Fittest Guys in the World in 2009, its clear that vegan athletes can and will leave competitors eating their dust.
