For the Corps By the Corps

The 17.75K is a uniquely Marine event. The distance reflects the year the Corps was established. The intended setting was Prince William Forest Park where finishers emerge from among the trees emulating the Marines at the Battle of Belleau Wood. Participants who cross the finish earn access to the Marine Corps Marathon. Hosted in 2020 as a virtual-only event, the 17.75K was available to runners to complete the required distance in remote locations. Only those registered for the original event and not the Virtual Open earned Access Granted.
