 For Matt Green, running as a kid was punishment. If you were an athlete growing up, it was like go run laps or you got to condition, you know, so you got to go for a run. But 11 years ago, a midnight birthday 5K with three college buddies changed his mind. The friends soon created the District Running Collective, a social run club that's taken off, especially among runners of color. It's created to be like a nice entryway into running with like group running. We're really trying to encourage folks to run.
