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

Anyone can do running. Running should be easy. It should be fun. It should include everyone. It shouldn't be a punishment for eating cheesecake, which is what we've turned it into.

Ask nothing from your running, and you'll get more than you ever imagined!

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.

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.

Deny your nature, and it will erupt in some other, uglier way.
