In true Rock ?n? Roll fashion, Washington DC runners will be treated to a post-race finish line concert after the event. All runners receive free entry to the concert, which in 2010 featured headliner acts including Everclear, Five for Fighting, Pat Benatar & REO Speedwagon, Blues Traveler, Neon Trees and Bret Michaels.
