In one of his most ambitious physical efforts to date, Dean Karnazes attempted to run 50 marathons, in 50 states, in 50 days to raise awareness of youth obesity and urge Americans of all fitness levels to "take that next step." "UltraMarathon Man: 50 Marathons - 50 States - 50 Days", a Journeyfilm documentary, follows Dean’s incredible step-by-step journey across the country. Ultrarunning legend Dean Karnazes has run 262 miles-the equivalent of ten marathons-without rest. He has run over mountains, across Death Valley, and to the South Pole-and is probably the first person to eat an entire pizza while running. With an insight, candor, and humor rarely seen in sports memoirs (and written without the aid of a ghostwriter or cowriter), Ultramarathon Man has inspired tens of thousands of people-nonrunners and runners alike-to push themselves beyond their comfort zones and be reminded of "what it feels like to be truly alive," says Sam Fussell, author of Muscle. Ultramarathon Man answers the questions Karnazes is continually asked: - Why do you do it? - How do you do it? - Are you insane? And in the new paperback edition, Karnazes answers the two questions he was most asked on his book tour: - What, exactly, do you eat? - How do you train to stay in such good shape?

The author, a freelance journalist, describes his experiences as a reporter and participant in the Raid Gauloises, an annual eight- to twelve-day race designed to test the limits of human endurance.
