Registration Opening Soon!
Annually ranked as one of the largest marathons in the US and the world, the MCM has been recognized as “Best Marathon in the Mid-Atlantic,” “Best for Families” and “Best for Beginners.” Organized by the men and women of the United States Marine Corps, the MCM is the largest marathon in the world that doesn’t offer prize money, instead celebrating the honor, courage and commitment of all finishers.
The Organization for Autism Research will be back at the Marine Corps Marathon and MCM 10K on October 31, 2021! Join the RUN FOR AUTISM team and help fund autism research and services! Sign up for the interest list and we'll email you when registration opens.
