About the Event

OSS/CIA 50 Mile Night Run

Register for the OSS/CIA 50 Mile Night Run on Saturday, June 13, 2026, at the Telegraph Road Pavilion in Triangle, VA. This event features a 50-mile course (25+ mile loop run twice) and a night marathon (starting at 11:55 PM). The course is primarily single track with some fire road and road crossings. Aid stations are located at the start/finish, halfway point, and two mini-aid stations. Crews are only allowed at the start/finish line. Pacers are allowed from the second loop.

Race and Course Information: The OSS/CIA 50-mile race is a 50-mile event. The course is a 25+ mile loop run primarily on single track, with some fire road, and several bridge and road (NPS road) crossings. The 25+ mile loop is run twice to give you 50+ miles. Starting in 2023, we will incorporate a night marathon into the fray. It will start at 11:55 p.m.. This will give athletes 8 hours and 35 minutes to complete the one loop event. All cut-offs in place for 50 mile will be incorporated into the night marathon.

Aid Stations: Two fully-stocked main aid stations at the start/finish (Telegraph road pavilion), and the halfway point for each loop (Oak Ridge Camp Ground). There will be two additional "mini-aid" stations with a smaller selection of food, and water and Tailwind located where South Valley Trail intersects Scenic Drive, and where Burma Road intersects Scenic Drive.

Crews/Pacers: Crews will only be allowed at the Telegraph Road Pavilion Start/Finish line. Pacers will be allowed for all runners beginning at the second loop from Telegraph Road Pavilion.

General information about the Park: The Prince William Forest Park established in 1936 has 37 miles of trails on its 15,000+ acres, and is the largest protected natural area in the Washington, D.C., metropolitan region.
