Dahlgren Heritage Rail Trail 50K
King George, United States • 2 Aug 2025
The Dahlgren Heritage Rail Trail 50K is a challenging ultramarathon held annually in King George, Virginia, along the scenic Dahlgren Railroad Heritage Trail. This flat, well-maintained, and mostly shaded out-and-back course covers 31 miles on a converted railroad bed featuring dirt, grass, pine needles, crushed stone, and small gravel surfaces. The race offers a supportive atmosphere with seven aid stations providing water, Gatorade, food, and PBJ sandwiches.
Participants face an 8-hour time limit to complete the course, which is known for its solid footing and minimal elevation changes. Awards include cash prizes and age group honors, with race swag featuring a technical shirt and finisher's medal. The event emphasizes environmental responsibility by adopting cupless racing and partners with Hammer Nutrition for on-course fueling. Visit the organization's website for the most recent information.
