“We wouldn't be alive without love we wouldn't have survived without running maybe we shouldn't be surprised that getting better at one could make you better at the other.”

“The words of the social critic Eric Hoffer were ringing true: "Every great cause begins as a movement, becomes a business, and turns into a racket.”

“But there's a problem," Dr. Bramble said. He tapped his forehad. "And it's right up here." Our greatest talent, he explained, also created the monster that could destroy us. "Unlike any other organism in history, humans have a mind-body conflict: we have a body built for performance, but a brain that's always looking for efficiency." We live or die by our endurance, but remember: endurance is all about conserving energy, and that's the brain's department. "The reason some people use their genetic gift for running and others don't is because the brain is a bargain shopper.”

“Every morning in Africa, a gazelle wakes up," Bannister said. "It knows it must outrun the fastest lion, or it will be killed. Every morning in Africa, a lion wakes up. It knows it must run faster than the slowest gazelle, or it will starve. It doesn't matter whether you're a lion or a gazelle - when the sun comes up, you'd better be running.”

“He was onto something. Something huge. It wasn't just how to run; it was how to live, the essence of who we are as a species and what we're meant to be.”

“The reason we race isn't so much to beat each other, he understood, but to be with each other.”

“After all, what else did we have going for us? Nothing, except we ran like crazy and stuck together. Humans are among the most comunal and cooperative of all primates; our sole defense in a fang-filled world was our solidarity, and there's no reason to think we suddently disbanded our most crucial challenge, the hunt for food. I remembered what the Seri Indians told Scott Carrier after the sun had set on their persistence-hunting days. "It was better before," a Seri elder lamented. "We did everything as a family. The whole community was a family. We shared everything and cooperated, but now there is a lot of arguing and bickering, every man for himself." Running didn't just make the Seris a people...it also made them better people.”

“Don't fight the trail, take what it gives you. If you have a choice between one step or two between rocks, take three.”

“You ran to eat and to avoid being eaten; you ran to find a mate and impress her, and with her you ran off to start a new life together. You had to love running or you wouldn't live to love anything else.”

“The Tarahumara would party like this all night, then rouse themselves the next morning to face off in a running race that could last not two miles, not two hours, but two full days. According to the Mexican historian Francisco Almada, a Tarahumara champion once ran 435 miles, the equivalent of setting out for a jog in New York City and not stopping till you were closing in on Detroit.”

“Way before we were scratching pictures on caves or beating rhythms on hollow trees we were perfecting the art of combining our breath and mind and muscles into fluid self-propulsion over wild terrain.”
