The fastest long-distance runners are from a secretive indigenous Mexican tribe called the Tarahumara. They’re so secretive, in fact, that they seldom race outsiders. When they do, they race in thin sandals and win easily. This may sound like an elaborate fiction, but it’s not. Christopher McDougall lived among them, learned their ways, and witnessed a race between this tribe and the best ultramarathoners in the world. You might disagree with some of his conclusions about how people came to love running, but you can’t help but be affected by his enthusiasm. (Knopf)
