Harvey Lewis is endurance. The ultrarunning champion and adventurer routinely pushes the limits of human capabilities, one step at a time. The winner of prestigious races like the Badwater Ultramarathon in Death Valley, and the Big Dog Backyard Ultra, a race with no finish line, Harvey discusses endurance, patience, and participating in the Barkley Marathon—the hardest race in the world. Marked with trademark humility and grace, Harvey’s wisdom is a gift.
