About the race
The PB&J 50k and 25k are trail competitions held in Prince William Forest Park on October 24, 2026. The event uses a runnable, rolling loop on shaded, undulating trails that include sections of smooth and technical singletrack, a creek, and swinging bridges. The start and finish area is at the Telegraph Road Pavilion near the park entrance. The course follows a lollipop format with two on-trail aid stations and an additional aid station at the start and finish.
Total ascent for the full course is about 2,500 feet. GPX files, a marked map, and a turn sheet are provided for both distances. The event is limited to 110 runners and entry is closed for this edition.
There is no formal entry fee; participants are asked to bring one aid station food or drink item for the common aid. Cutoffs and distance structure are published for each competition. The 25 km competition consists of one 16 mile loop with a 4 hour time limit. The 50 km competition consists of two identical 16 mile loops; the first loop has a 4 hour time limit and the full distance has a 9 hour time limit. Volunteers support aid stations and race operations.
Medical support is not provided by the club; runners are responsible for their own health and emergency care may be distant in remote areas. Visit the organization's website for the most recent information.
