Redeye 50 km : Prince William Forest Park
Redeye 50 km takes place on Fri Jan 1, 2027 and starts at the Pine Grove Picnic Area in Prince William Forest Park. The full distance is 31.7 miles run as three repeats of a roughly 10 mile loop.
The first loop includes a 2.5-mile prologue on the Birch Bluff Trail, making that leg about 11.9 miles. The prologue uses 0.5 miles of pavement to Telegraph Road Pavilion, then about 1.5 miles of trail to the swinging bridge over Quantico Creek, followed by a 9-mile counter-clockwise loop and 0.45 miles up Laurel Trail back to Pine Grove. Loops two and three repeat the 9.9-mile counter-clockwise circuit. Terrain is primarily groomed forest trails with two 1-3 mile sections of rolling gravel roads. The course is marked to be run counter-clockwise but loops may be reversed by runners familiar with the route.
An unmanned aid station is located at the start/finish and is accessed at the end of each loop. The aid spread is traditionally supplied by runners and often becomes a shared food table. Restrooms are available above the main parking area, adjacent to the visitor center, and near the Turkey Run Education Center about seven miles into the loop. A GPX file, turnsheet, and park map are available for download.
Entry opens Tuesday December 1, 2026 at 9:00 am and is limited to 120 runners. Entrants must pay the National Park Service entrance fee on the way out; cash is no longer accepted. The event does not provide medical personnel or medical supplies; runners are responsible for their own health and safety and emergency response may be delayed in remote areas.
