On July 20, Trials of Miles Racing, REI Co-op, and On are teaming up to throw a summer block party on the streets of D.C. The party will revolve around a series of races on a 1/2 mile long closed loop course that will start and finish in front of Lost Generation Brewing Company. Runners can expect big crowds and high energy on a small course specifically designed for the spectators to take in all the action. The schedule will feature several sections of 5k's, with some fun additional races mixed in -- like a 4x800 relay, an elimination mile, and kids 800m race.

After you’re done competing stick around for a beer from Lost Generation or a bite from one of the several food trucks that will be standby. It’s an all-day block party with entertainment for all ages.
