Whether or not you're running this weekend at the Marine Corps Marathon, you could be affected by weekend road closures if you're in D.C. or Arlington — and that will include the shutdown of the Key Bridge from about 5:30 a.m. to 10:30 a.m. Sunday morning.
MCM events are scheduled for both Saturday and Sunday, including the marathon itself, other races, a kids’ fun run and a finish line festival. (We've got a complete guide for both runners and spectators here.)
