The Experience
The Dahlgren Trail Half Marathon winds its way along a flat, smooth path on an old railroad bed, offering a scenic and straightforward running experience. This out-and-back course, first run in 2010 and now in its 17th year, provides a peaceful setting for runners.
With a typical field size of around 360 finishers, the race fosters a sense of community, with about 30% of participants returning year after year. Runners from approximately 4 states have converged on this event, drawn by its unique charm and the promise of a memorable day.
The finish is marked by more than just a medal; participants can enjoy good food, including the novel experience of roasting Krispy Kreme donuts over a campfire, and cash prizes add an element of competition. The race, which starts at 9:00 am to accommodate cooler January temperatures, offers a generous 3.5-hour time limit, making it accessible for a wide range of runners.
