Bigger than big. The MCM welcomes a new distance to conquer when the MCM50K is inaugurated on October 27. The MCM50K shares a start line with the Marine Corps Marathon in Arlington, VA. Participants will begin the MCM50K prior to the Marathon and run the entire MCM course with the addition of a 4.87-mile diversion at Mile 4.5.


Registration is now closed. All participants receive a technical quarter zip shirt and finishers are presented with a stunning finisher medal by a U.S. Marine. Registration fee is $200.

Consult sizing chart to determine best fit of participant shirt.


After registering for the MCM50K, some runners unfortunately are unable to participate. These runners may opt to transfer their entry to a non-registered runner through the Transfer Program. The MCMO doesn't assist in the identification of individuals to receive a transfer. Runners often find transfer partners on the MCM Facebook page.

Runners currently registered for the MCM50K may transfer an entry to another runner. There is a $50 transfer fee (plus processing) associated with transferring between individuals. Either individual involved in the transfer may pay this fee, it is the current owners choice.

When transferring an entry, runners do not receive a refund on registration fees. Any such monetary transactions must be handled directly between the transferring runners.
