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.

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.

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.

Were designed for persistence hunting, which is a mix of running and walking. Whats built into that kind of running is a sense of pleasure. You are designed and built and perfect for this activity, and it should be enjoyable and fun.

Blaming the running injury epidemic on big, bad Nike seems too easy - but that's okay, because it's largely their fault.

We've created an unnatural form of running. It's not just the shoes, but we run on artificial surfaces - straight ahead, hard and steady - instead of speeding up and slowing down, reacting to the terrain with changes of pace and rhythm.

If you don't have answers to your problems after a four-hour run, you ain't getting them.
