Runners are a fractious and varied group. It’s nearly impossible to generalize about them, except to say that individuality is core to their identity. By definition they live outside the law, and as a consequence they mostly lead a solitary existence. They do not have overarching organizations or affiliations, or indeed much of anything that makes any one runner similar to another. They come from all walks of life, vary dramatically in skill sets, goals, and available resources, and don’t even have a dress code.
