I have the idea that running shoes are based on a kind of cult idea - that our feet are flawed and we need shoes to correct those flaws. The shoe companies are in the business of selling shoes. But there's no evidence from running shoe manufacturers that they're right. There's no scientific data that running shoes reduce injury.

Humans are built for endurance, not speed. We're awful sprinters compared to every other animal. We try to run our races as if they were speed races, but they are not. They're endurance races. Even a marathon, the way it's run now, it's not an endurance contest.

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.

Make friends with pain, and you will never be alone.~Ken Chlouber, Colorado miner and creator of the Leadville Trail 100 mile race

Running is the heart of what it means to be human.

Everyone is built for running.

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.
