About This Race
The 3H Trail Half Marathon and DHRT 50K takes its name seriously—this August race in King George, Virginia, is known for being Hot, Hazy, and Humid. Set along the scenic Dahlgren Railroad Heritage Trail, this event offers runners two distance options on what organizers describe as a beautiful, mostly flat rail-trail surface. The race begins early at 6:30 AM to help runners beat the worst of Virginia's summer heat, though conditions remain challenging throughout the morning. Both the half marathon and 50K distances follow an out-and-back course format on the converted railroad corridor, providing a straightforward navigation experience on smooth trail surfaces. All participants receive a technical tank top and finisher's medal. With up to 500 runners expected across both distances, this race attracts those seeking either a solid half marathon trail experience or a more accessible ultra distance on forgiving terrain.
