3H Trail Half Marathon - King George, VA

The 3H Trail Half Marathon in King George, Virginia, is a scenic, flat, and fast out-and-back race held entirely on the Dahlgren Railroad Heritage Trail, a converted railroad bed featuring dirt, gravel, grass, and pine needle surfaces. The course offers nearly 100% shade from surrounding trees, providing a comfortable running environment despite the August heat and humidity. The trail preserves natural beauty and wildlife across 16 miles in King George County.

Participants receive a custom finisher medal and technical tank top, with aid stations offering water, Gatorade, and snacks. The event emphasizes environmental care with cupless racing and supports the volunteer-run Friends of the Dahlgren Rail Heritage Trail.
