Dahlgren Heritage Rail Trail Events

The 3H Trail Half Marathon and the Dahlgren Heritage Rail Trail 50K take place in King George, Virginia. Both events are held on a rails-to-trails course that is mostly flat and smooth. The routes are designed as out-and-back courses. While much of the terrain is even, certain sections contain roots and bog boards that require participants to use extra caution.

Participants may choose between two distances:

  • 13.1 miles (Half Marathon)
  • 50 km

The event is open to both runners and walkers. Participants must adhere to specific time limits based on their chosen distance. The half marathon has a time limit of 4 hours, while the 50K distance has an 8-hour time limit.

Individuals who complete the course receive a finisher's medal and a choice of either a tank top or a t-shirt. The event includes cash prizes for competitive participants. Aid and refreshments are provided, with food available for those taking part in the races. Registration for these events typically opens in October and closes in early December of the preceding year.
