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 because it always takes me where I want to go.

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.

A lot of ultramarathoners are soloists. They're single and live lives off the grid.

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

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