There's something so universal about that sensation, the way running unites our two most primal impulses: fear and pleasure. We run when we're scared, we run when we're ecstatic, we run away from our problems and run around for a good time.

In 'Tarahumara' land, there was no crime, war or theft. There was no corruption, obesity, drug addiction, greed, wife-beating, child abuse, heart disease, high blood pressure, or carbon emissions. They didn't get diabetes, or depressed, or even old: 50-year-olds outran teenagers.

Running should be free, man.

But you can't muscle through a five-hour run that way; you have to relax into it like easing your body into a hot bath, until it no longer resists the shock and begins to enjoy it.

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

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.

...there was some kind of connection between the capacity to love and the capacity to love *running*. The engineering was certainly the same: both depended on loosening your grip on your own desires, putting aside what you wanted and appreciating what you've got, being patient and forgiving and... undemanding...maybe we shouldn't be surprised that getting better at one could make you better at the other.
