Adventure books are my personal favorites. 'The Endurance,' a story about Ernest Shackleton's legendary Antarctica expedition, or 'Into Thin Air,' Jon Krakauer's personal account of the 1996 disaster on Mt Everest, are two notables.

A Marathon is not about running, it is about salvation. We spend so much of our lives doubting ourselves, thinking we're not good enough, not strong enough, not made of the right stuff. The Marathon is an opportunity for redemption. "Opportunity," because the outcome is uncertain. "Opportunity," because it is up to you, and only you, to make it happen; only you can turn your farfetched dream into a reality.

Don't confuse comfort with happiness.

I love to run and I have some tips to keep it fresh and novel. I rarely use the same route twice. That keeps things new.

I run because it always takes me where I want to go.

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.

I wasn't born with any innate talent. I've never been naturally gifted at anything. I always had to work at it. The only way I knew how to succeed was to try harder than anyone else. Dogged persistence is what got me through life. But here was something I was half-decent at. Being able to run great distances was the one thing I could offer the world. Others might be faster, but I could go longer. My strongest quality is that I never give up.
