About the Trick or Treat 5k

The course runs through Green Lake Park, circling the lake on paved paths. It is a flat route with the water visible for most of it, and the fall timing means plenty of runners show up in costume. The park stays busy on weekend mornings, so expect to share the path with dogs and strollers alongside the race field.
