The Marine Corps Marathon returns on Sunday, 25 October, with more than 30,000 runners and an estimated 100,000 spectators expected in and around Washington, D.C. According to the official Marine Corps planning message, it is the largest annual single-day community relations event the Marine Corps stages, and is organised by the Marine Corps Marathon Organization from Marine Corps Base Quantico in Virginia.
The weekend begins on Saturday, 24 October with the MCM Kids Run and the opening ceremony for the Armed Forces Marathon Championships, which are held within the race. Medical coverage is provided through the Naval Medical Readiness Training Command at Quantico, with a chemical-biological consequence management advisor supporting the event.
The race also arrives in the middle of a live debate about qualifying times. The Marine Corps Marathon is not a USATF-sanctioned race, and USATF's Jay Holder has said the federation handled the Marine Corps Marathon the same way as Baystate: times run there do not count towards the 2028 U.S. Olympic Marathon Trials standards. Last year's women's winner, Tessa Barrett, ran 2:34:11 in Washington and later secured her Trials qualifier with a 2:30:11 at the California International Marathon.
For the overwhelming majority of the field, that is not a concern, and the event remains one of the biggest on the autumn calendar in the United States. Runners should check the official race channels for course, road closure and start-time details, which were not specified in the planning message.
The race comes one week before the TCS New York City Marathon on 1 November, and on the same day as the Dublin and Frankfurt marathons in Europe, making 25 October one of the busiest days of the autumn road season. For the Marines and the tens of thousands of civilian runners alike, the focus will be on race day itself.
