The 'Tarahumara' use their legs 'as designed.' By running at a young age with minimal footwear, they naturally develop the best biomechanical use of their legs. Cushioned shoes restrict foot movements and allow for over-striding. Short strides are natural.

That was the real secret of the Tarahumara: they'd never forgotten what it felt like to love running. They remembered that running was mankind's first fine art, our original act of inspired creation. 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. And when our ancestors finally did make their first cave paintings, what were the first designs? A downward slash, lightning bolts through the bottom and middle-behold, the Running Man.

We've got a motto here-you're tougher than you think you are, and you can do more than you think you can.

If you can run six miles on a summer day, then you, my friend, are a lethal weapon in the animal kingdom.

When it comes to mentors, you can't beat survival.

There is a growing subculture of barefoot runners, people who got rid of their shoes. And what they have found uniformly is you get rid of the shoes, you get rid of the stress, you get rid of the injuries and the ailments.

The only way to truly conquer something, as every great philosopher and geneticist will tell you, is to love it.
