Dahlgren Trail Half Marathon

King George, United States • 16 Jan 2027

Dahlgren Trail Half Marathon

The Dahlgren Trail Half Marathon takes place in King George, Virginia. The event features a single distance:

  • 13.1 Miles

The course is set on the Dahlgren Railroad Heritage Trail, following a scenic out and back route. Participants run on an old railroad bed characterized by its flat and smooth surface. Because the event occurs in January, the race is scheduled to allow for warmer temperatures during the run.

The race has a strict time limit of 3.5 hours, which requires participants to maintain a pace of approximately 16 minutes per mile. All finishers are awarded a custom race medal. Event amenities include a t-shirt for those who register before the deadline, and post-race food is provided, featuring an opportunity to roast donuts over a campfire. Cash prizes are available for top competitors.

Registration for the event typically opens in March of the preceding year. The event site is located at 10431 Bloomsbury Road, offering a natural environment for trail running on a retired railway corridor. Visit the organization's website for the most recent information.
