Running unites us and brings us together because, in the words of the great Bill Rodgers, “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.
