He's run 350 continuous miles, straight through three nights without sleep. He's run across Death Valley in the middle of summer, where temperatures reached 128 degrees, and he's run a marathon to the South Pole in negative 40 degrees. On seven separate occasions, he's run a 200-mile relay race solo, racing alongside teams of twelve.

Ultramarathon Man has received gleaming reviews in Publisher's Weekly, Esquire, Newsday, Sports Illustrated, and myriads of others, and is currently in print in ten languages.
