Course, aid and logistics
Both courses run entirely on the Dahlgren Railroad Heritage Trail, a converted rail bed that is mostly flat and smooth with surfaces of dirt, gravel, grass, and pine needles. The course is an out-and-back that starts on the eastern end of the trail and heads west for about 6.5 miles before turning back. The trail is largely shaded and follows a 16-mile corridor of the old Dahlgren Branch rail line.
Water is available near miles 3.3, 6.5, 9.8 and 12.2; Gatorade is provided at miles 3.3, 6.5 and 9.8. Aid station food at the Panorama location is primarily for 50K participants. A crossing guard will assist at major road crossings. Packet pickup dates and locations are listed for August 1-2, 2025. Race day parking is at King George Gateway Shopping Center.
