The Experience
The 3H Trail Half Marathon winds its way through King George, Virginia, along the scenic Dahlgren Railroad Heritage Trail. This out-and-back course is primarily flat and smooth, though runners should be mindful of occasional roots and bog boards that add a touch of trail challenge.
With a typical August race-day temperature hovering between 69–86°F, the heat is part of the challenge, but the smooth, mostly flat terrain offers a good opportunity for runners and walkers alike. The event, first run in 2016 and now in its 10th edition, draws participants from around 11 states.
Finishers are rewarded with a choice of a tank top or t-shirt, a medal, and post-race treats including free MooThru ice cream. Cash prizes are also up for grabs for top competitors, making for a memorable event with a 4-hour time limit.
