When I run, I’m an invisible observer of my city, a ghost forgotten by the people I pass almost as quickly as I disappear from view. I’ve gotten a broad, hard look at this city and its people. Some of it is challenging to see, but at times I think I can see the things that connect every citizen of the city. … We run across the invisible divides that segregate us from neighbors and, in that way, we come to understand where we live.
