Unless you're not pushing yourself, you're not living to the fullest. You can't be afraid to fail, but unless you fail, you haven't pushed hard enough."

Any goal worth achieving involves an element of risk.

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.

Don't run with your legs, run with your heart.

Once you permit yourself to compromise, you fail yourself.

I run with a credit card and a cell phone, so when there is not a 7-Eleven around, like some of the country roads out there, I can get him to deliver a pizza to me. And I kind of give them a coordinate, a corner.

As long as my heart's still in it, I'll keep going. If the passion's there, why stop?... There'll likely be a point of diminishing returns, a point where my strength will begin to wane. Until then, I'll just keep plodding onward, putting one foot in front of the other to the best of my ability. Smiling the entire time.
