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.

I run to breathe the fresh air. I run to explore. I run to escape the ordinary.

I have an ElliptiGO. It's a standup bicycle. You don't pedal; you stride on it. It allows me to have the same striding motion as running without the impact.

Somewhere along the line we seem to have confused comfort with happiness.

The human body has limitations. The human spirit is boundless.

I'm not trying to take more of the pie for myself. I'm trying to make the pie larger for everyone.

Runners are competitive folks. I think some might feel slighted they haven't got more recognition. I think they have a point. In running, you won't necessarily get noticed just for turning in good performances.
