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.

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.

How to run an ultramarathon ? Puff out your chest, put one foot in front of the other, and don't stop till you cross the finish line.

I don't know about you, but all this modern technology that's supposed to save us time and effort has actually ended up making things more complicated in my life, eating up extra time.

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 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. Furthermore, I run to explore. Furthermore, I run to escape the ordinary. Furthermore, I run…to savor the trip along the way. Life becomes a little more vibrant, a little more intense. I like that.

I run because long after my footprints fade away, maybe I will have inspired a few to reject the easy path, hit the trails, put one foot in front of the other, and come to the same conclusion I did: I run because it always takes me where I want to go.

It had been said that the marathon doesn't really begin until mile twenty. I say mile twenty-six would be more appropriate. The final two-tenths of a mile is filled with emotion. No matter how desperately you're struggling at this point, thoughts typically drift away from the immediate task at hand (i.e., survival) to broader feelings.

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.

People think I'm crazy to put myself through such torture, though I would argue otherwise. Somewhere along the line we seem to have confused comfort with happiness. Dostoevsky had it right: 'Suffering is the sole origin of consciousness.' Never are my senses more engaged than when the pain sets in. There is a magic in misery. Just ask any runner.
