“The first thing I do when I walk into a hotel is find the gym, and if they don't…” — Dean Karnazes

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.

Any goal worth achieving involves an element of risk.

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.

I do a lot of marathons as training runs. If I'm somewhere and there's a marathon, I'll sign up and just go run it.
