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.

Struggling and suffering are the essence of a life worth living. If you're not pushing yourself beyond the comfort zone, if you're not demanding more from yourself - expanding and learning as you go - you're choosing a numb existence. You're denying yourself an extraordinary trip.

I eat nothing that's processed or refined - no high-fructose corn syrup, no sugar, no trans-fats. I eat a lot of fish and monounsaturated fats from olives, olive oil and nuts. A lot of organic, fresh fruits and vegetables. No bread. No gluten. No wheat. No rice.

Running unites us and brings us together because, in the words of the great Bill Rogers, "We sweat the same. We struggle the same." 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. Toeing the starting line of a marathon, regardless of the language you speak, the God you worship or the color of your skin, we all stand as equal. Perhaps the world would be a better place if more people ran.

I never feel more alive than when I'm in great pain, struggling against insurmountable odds and untold adversity. Hardship? Suffering? Bring it!

Somewhere along the line we seem to have confused comfort with happiness.

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.
