“World’s Toughest Motorcycle Riders”—long-distance motorcycling is not a pastime but an obsession. In this candid, eloquent, sharply observed book, Melissa Holbrook Pierson introduces us to this strange endeavor and the men and women who live to ride impossibly long distances, eating up road, almost without cease. And who find it nothing but fun.

Perhaps the most determined of them is John Ryan, a magnetic, enigmatic man who loves nothing better than breaking records of amazing distance—at no small risk to himself and his health. But why? Pierson, who rediscovered the joys of motorcycling in the midst of a personal crisis, puts on her helmet and joins Ryan in his element in order to understand his singular desire and discipline, his passion and his obsession.

The Man Who Would Stop at Nothing offers an intimate glimpse of an unusually independent yet supportive community as well as a revealing, unforgettable portrait of its most daring member. In electric, pitch-perfect prose, Pierson gives us rare insights into not only a subculture but also the deeply human craving for something more that drives it.
