PB&J 50k + 25k

The PB&J is a trail competition held in Prince William Forest Park. The event uses a lollipop course on shaded, rolling trails with a mix of smooth and technical sections, creek crossings, and swinging bridges. The marked route is the same for both distances.

Distances:

  • 50 km two identical 16-mile loops
  • 25 km one 16-mile loop

There are two on-trail aid stations, Mawavi Road and Turkey Run Education Center, plus a Start/Finish aid station located mid-loop. Mile splits along the course include roughly 7.3 miles, 12.8 miles, and 16.0 miles per loop. Runners are asked to bring one donated food or drink item for the common aid; volunteers often provide additional food at stations.

Cutoffs and limits: each loop has a 4 hour time limit, and the full 50k has a 9 hour time limit. Field size is limited to 110 runners and registration is currently at capacity.

Practical notes: GPX files and turn directions are provided for both distances. Park entrance fees apply per vehicle at the park visitor center. The event does not provide medical personnel or medical supplies along the course; runners are responsible for their own health and safety. Volunteers support aid stations and event operations.
