Register for the Marine Corps Marathon Weekend

Recognized for impeccable organization on an iconic course managed by the US Marines in Arlington, VA and the nation’s capital, the Marine Corps Marathon is one of the largest marathons in the US and the world. Known as ‘the best marathon for beginners,’ the MCM is the largest marathon in the world that doesn’t offer prize money, earning its nickname, “The People’s Marathon.” The weekend also offers the MCM10K and MCM50K.
