Marine Corps Marathon 2024: Routes and road closures around D.C.

Driving the news: "The People's Marathon," one of the largest in the world, blasts off on Sunday at 7:55am around the Pentagon and finishes at the Marine Corps War Memorial Circle.

• There are five main viewing locations along the race course, which is slightly different this year due to construction around Ohio Drive SW, plus apps to track runners.

Road closures: A large number of roadways and parts of I-395 will be closed in Arlington and the District on Sunday, starting as early as 3am and ending around 6pm.

• Parking will be restricted in areas along the race routes. On Saturday, Boundary Channel Drive from N/S Connect Road to Route 110 will be closed 6:30am-1:30pm.

More races, events: Paid registration is still open for a kid's fun run on Saturday (ages 5-12), and a shorter 10K run and 50K ultra-marathon on Sunday.

• Head to a free Finish Festival in downtown Rosslyn on Sunday (8am-4pm) for beer, food, and live music.

The intrigue: Metro will open early at 5am on Sunday for the event.

• MCM organizers recommend taking Metro, using drop-off locations, or shuttles given the road closures.
