San Diego After Dark Dash 5k, San Diego

Many 5K races try to drum up enthusiasm with costume contests, obstacles, and other bells and whistles. But not the After Dark Dash. As its official website states, the race promises, “No fads. No gimmicks. Just you, the pavement, and the city lights.” Yes, this race is all business—at least, until the race ends, when runners are treated to beverages, fresh eats, and music at a local hangout.

The race series takes over four US cities—San Diego, Sacramento, Boise, and Denver—and uses the simplicity of the city lights as a backdrop for each meditative jaunt. Courses zigzag through some of the hippest neighborhoods and historic districts in town, presenting runners with the chance to simultaneously explore new areas and the limits of their tender Achilles tendons.
