King George, United States • 8 Aug 2026

Event overview

The 3H Trail Half Marathon + DHRT 50K is scheduled for Saturday, August 8, 2026, in King George, VA (4224 University Drive, 22485). The event features two races:

  • 3H Trail Half Marathon
  • Dahlgren Heritage Rail Trail 50K

Time limits are four hours for the half marathon and eight hours for the 50K. All participants receive a custom finisher medal and a technical tank top or t-shirt; shirts are not guaranteed after July 21, 2026.

Course and logistics

Both races run entirely on the Dahlgren Railroad Heritage Trail, a 16 mile rail-to-trail route across King George County. The course is an out-and-back that begins at the eastern end of the trail and heads west for about 6.5 miles before turning back. Surfaces include dirt, gravel, grass, and pine needles; the converted railroad bed provides solid footing with little or no roots. Trees along the trail provide almost 100% shade.

Aid stations provide water near miles 3.3, 6.5, 9.8 and 12.2; Gatorade is at miles 3.3, 6.5 and 9.8. The Panorama aid station supplies food primarily for 50K participants. A crossing guard will assist at major road crossings. Packet pickup occurs August 1 and August 2, 2025 at listed local locations, and race day parking is available at the King George Gateway Shopping Center. The event uses a cupless policy; runners should bring their own hydration vessel or HydraPak SpeedCup. Awards include cash prizes for overall finishers and age-group awards; detailed prize amounts and course-record bonus information apply.
