The author describes his work with Caballo Blanco, an outsider who befriended the Tarahumara Indians, in which the two men organized a running event between the tribesmen, who are considered to have superhuman running abilities, and Americans, including a ultramarathoner, a surfer, and others; and includes facts about techniques and the history of running.
