The unspoken and shared understanding of what it means to be a runner can be seen in the kinship between runners. When 40,000 people line up to run the Chicago Marathon, or when 130 line up at a high school cross-country race, they can look each other in the eye with a certain respect, awareness, and comprehension that is prohibitively elusive for the non-runner. Before, during, and after the race, the fellowship between runners is tangible and real. The brotherhood and sisterhood of the running community can be felt in the air as they inhale a collective like-mindedness. To be a runner in the midst of other runners just before the start of a race is a mystical experience that can no more be captured in words than can the color blue.
