Updated Oct. 27: the race ran Sunday, Oct. 25, and all of these closures have ended. The organizer lists the next Marine Corps Marathon for Sunday, Oct. 31, 2027; our Marine Corps Marathon page will carry its closures.

Arlington County police will close dozens of roads in Rosslyn, Pentagon City and Crystal City on Sunday for the 51st Marine Corps Marathon. The first closures start at about 3 a.m., and the longest run until about 6 p.m.
