I have my whole office set-up at waist level; I don't sit at all during the day. Sitting, to me, is the devil.

There is magic in misery. Just ask any runner.

Run when you can, walk if you have to, crawl if you must; just never give up.

I run because long after my footprints fade away, maybe I will have inspired a few to reject the easy path, hit the trails, put one foot in front of the other, and come to the same conclusion I did: I run because it always takes me where I want to go.

I love surfing, rock climbing, cycling - all that stuff. But it's just amazing that I can inspire people with my running. It's humbling, really.

Awakenings are always terrifying as they force you to realize your past has been lived in confinement, the most disturbing part is when you recognize that the shackle holding you down are largely once you have placed upon yourself, the prison is self constructed

If someone had said to me before I started doing this that a human being is capable of running 100 miles nonstop, I would have just said: 'No way. I mean, how?' If you just go out there and run 100 miles, it breaks down a lot of barriers in terms of self-imposed limitations.
