Born to Run: A Hidden Tribe, Superathletes, and the Greatest Race the World Has Never Seen

The summary

Distance running should not wreck your body. For most of human history it didn’t. Your anatomy was shaped by persistence hunting—chasing animals across open ground until they dropped from heat exhaustion—which means the body is engineered to cover long distances. So why do 65 to 80 percent of modern runners get hurt every year, with doctors telling the injured to simply stop? Christopher McDougall’s answer is that the fault isn’t in running. It’s in the cushioned shoes that numb the feedback your feet need, and in treating running as a chore instead of the pleasure it was born to be.

The tribe that runs hundreds of miles

The clue is a group of people who don’t get injured. Deep in Mexico’s Copper Canyons live the Tarahumara, who run staggering distances over jagged terrain in nothing but thin sandals—one runner reportedly covered 435 miles without stopping. They don’t train. Running is simply part of who they are, celebrated in rarájipari, a traditional game where players kick wooden balls ahead of them across 50 or 60 miles, sometimes all night. A 1971 study called them the fittest people since the ancient Spartans. They live long, egalitarian lives largely free of heart disease and depression. What they never lost is the childhood sense that running is a joy.

Your body is a persistence hunter

We evolved to do this. Standing upright expanded our lung capacity for endurance; the Achilles tendon, arched feet, and powerful glutes act like springs that fling us forward efficiently. Four-legged animals can sprint, but galloping restricts their breathing and they can’t sweat to cool off, so over long distances a patient human wins. That heritage runs deep: a 64-year-old can outpace a 19-year-old, and in ultramarathons women often beat men, with the gap shrinking as the distance grows. As McDougall puts it, you don’t stop running because you get old—you get old because you stop running.

The shoes are the problem

If we’re built for it, why the injuries? The footwear. Studies link expensive running shoes to a 123 percent higher injury rate than cheap, flat-soled ones. Cushioning is the culprit: it hides the painful impact that would otherwise tell you your form is wrong, so you keep landing badly. Run barefoot and every step gives instant feedback—land poorly and it hurts, so you adjust and find a safe gait on your own. The natural inward roll of the foot, pronation, is real shock absorption, but shoe companies sold it as a defect to move “corrective” models. Thick soles also cage the foot, weakening the muscles and tendons meant to do the work. Barefoot Ted, a serious ultrarunner, cured chronic back pain simply by ditching his shoes. The Tarahumara, in sandals or nothing, stay whole.

Run for joy, then train like the Tarahumara

The other half is why you run. Treat it as a means to an end—punishment for eating, a box to tick—and you’ll learn to hate it. Ultrarunners keep going for love of the act; there’s little fame or money in it. Micah True, a former California boxer who became Caballo Blanco, the White Horse, walked away from modern life to live among the Tarahumara, adopting their sandals, their pinole-corn diet, and their brutal trails, and grew healthier and happier for it. He organized a 50-mile race in the canyons pitting Tarahumara runners against American stars, including elite ultrarunner Scott Jurek.

To prepare, McDougall trained under coach Eric Orton with a back-to-basics plan: form, strength, pace, and diet. He used a metronome to learn the Tarahumara’s quick, light foot turnover, ran in flat-soled shoes, and shifted to a mostly vegetarian diet of pinole and chia—maximum nutrition from the fewest calories, with carbs that digest fast and leave no bulk to haul. Jurek and many top ultrarunners eat the same way. The guiding mantra was simple: easy, light, smooth, and fast—get the first three and speed takes care of itself. McDougall shed 25 pounds, felt better, ran faster, and stopped getting hurt. He finished the grueling Copper Canyon race; the Tarahumara’s Arnulfo Quimare won it, beating Jurek.

The bottom line

If running hurts you, the problem is almost never running itself—it’s cushioned shoes that mute the signals your feet use to protect you, and a mindset that turns movement into a chore. Strip both away and the body remembers what it was made for. Read this if a doctor has told you to quit, or if you want to feel again what it was like to run as a kid, for no reason but the running.
