When I was running across the country, I was doing 40 or 50 miles a day in sleeting snow with zero visibility for five or six days in a row. Ten to 12 hours of running in that is monotony beyond belief.

When I ran across America, for 75 days I ate 10,000 calories a day. I still lost about five pounds.

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.

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'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.

I am always nervous before the start of a race. It helps me to say to myself to try my very best. That is my commitment. No matter how bad it gets, I will try my hardest.

Yes, my dad's a marathoner. He used to do sprint distances and then started marathoning. My mom is an endurance animal. She does three-day events like the Susan G. Komen three-day walk.

Personally, I don't stretch, I don't get massages. Maybe massages would be useful, but I just don't have the time for it.

Unlike the traditional athlete, I've got to do more than just engage in my sport to put food on the table. When I'm done running, it's straight to the office.

Beyond racing, I just love the art form of running, of conceiving new ideas like the 50 Marathons in 50 States in 50 Days. It's the ultimate expression of what I love to do, which is run, and travel, and see this great country.

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

The first thing I do when I walk into a hotel is find the gym, and if they don't have a gym, I start looking for a handhold where I can do my pull-ups. Sometimes if a shower curtain rod is sturdy enough, I'll do them there.

To an extreme athlete, there's a certain appeal to doing extreme things - seeking the most extreme physical challenges in some of the most extreme climates in the world. Testing and expanding the limits of human endurance is kind of my thing.

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.
