I've raced on all seven continents at least twice. I've probably run thousands of races. But the single race that I'm most proud is a 10K. Yes, a 10K. I ran it with my daughter on her 10th birthday.

Running is a simple, primitive act, and therein lays its power. For it is one of the few commonalities left between us as a human race.

I went to college, grad school. I got an M.B.A., had a really cush corporate job. But I was just bored stiff. I didn't fit that mold.

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.

Running back-to-back races requires a certain tactical prudence. Going too hard in any one race might jeopardize your performance in another. Maintaining proper hydration and caloric equilibrium also becomes increasingly critical.

I run because if I didn’t, I’d be sluggish and glum and spend too much time on the couch. I run to breathe the fresh air. I run to explore. I run to escape the ordinary. I run…to savor the trip along the way. Life becomes a little more vibrant, a little more intense. I like that.
