The Marine Corps 17.75K course in scenic Prince William Forest Park features a 11.03 mile run over rolling hills and winding turns in a densely wooded backdrop. The 17.75K starts and finishes outside Montclair Tabernacle Church located in Dumfries VA, near Marine Corps Base Quantico and sends runners on a course through Prince William Forest Park.

Coronavirus (COVID-19) Update. Due to the impact and development of coronavirus (COVID-19) and under the guidance of government and health officials, the 2020 Marine Corps 17.75K, scheduled for March 28, and the accompanying Motivational Dinner, have been cancelled. We know that this is disappointing news for our running community, therefore we are offering all registrants our best options moving foward.


The Marine Corps 17.75K course begins just outside Montclair Tabernacle Church as runners head north (in a secured southbound lane of Route 234 and along the paved shoulder) before quickly turning left onto the gravel pathway of Pleasant Road to enter Prince William Forest Park.

The lollipop course begins with approximately two miles of gravel terrain beginning on Pleasant Road and turning right onto Burma Road. Runners then cross over Scenic Drive and travel downward on Taylor Farm Road before turning left onto Old Black Top Road (both roads are gravel).

Runners then turn right onto Scenic Drive, traveling clockwise. Near Mile 9, runners will make a left turn back onto Burma Road, heading toward the finish. Runners will complete a short out-and-back portion just before turning back onto Pleasant Road. Once on Pleasant Road, runners will continue straight until the final right turn, where they will exit Prince William Forest Park and follow the bicycle path to the 17.75K finish.

Runners must maintain 20 minute miles at the 17.75K.

There will be five water points along the course, at approximately the miles listed below:
