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.

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.

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.

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.

Run when you can, walk if you have to, crawl if you must; just never give up.

I have an ElliptiGO. It's a standup bicycle. You don't pedal; you stride on it. It allows me to have the same striding motion as running without the impact.

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.
