Marine Corps Marathon 2027 : the course km by km, race week and travel

The organiser’s own summary is the shape of the day: runners “begin between the Pentagon and Arlington National Cemetery”, go “through Rosslyn”, cross into the District “to tour Georgetown and the National Mall before ‘beating the bridge’”, then return to Arlington, “passing the Pentagon, winding through Crystal City, and finishing uphill” at the Marine Corps War Memorial. The course is USATF-certified. In running terms it is a hill, a long flat middle raced against the clock, and a short climb at the end. The kilometres and heights below are measured on the 2026 course; no change for 2027 had been published.

Km 0 to 6: the hill comes first

The gun goes on Route 110, with Arlington National Cemetery on the left in the first few hundred metres. The road runs north into Rosslyn, turns onto Wilson Boulevard at km 1.2 and North Lynn Street, and at about km 2 joins Langston Boulevard. This is the climb of the race: the road rises 59 m in the first 3.7 km, to 66 m above sea level at km 3.72, the highest point of the day. More than half of the course’s 112.4 m of climbing is done before km 4.

Then it all comes back. Spout Run Parkway drops from about km 4.3 to the George Washington Memorial Parkway by the Potomac at km 5.8, and by km 6 the course is down to about 6 m. A runner who holds goal pace up Langston Boulevard spends effort the flat middle will ask for later. Run the first 4 km on effort, and let the descent give the time back.

Km 6 to 9: Key Bridge and Georgetown

The course crosses the Potomac into the District on Key Bridge, from km 6.77 to 7.26, and runs M Street through Georgetown to Wisconsin Avenue at about km 7.8. The organiser’s mile 5 entertainment is the Georgetown Phantoms. K Street, 27th Street and Virginia Avenue lead down to Rock Creek Parkway at km 9.1. From km 6 to the finish the course never rises above 20 m.

Km 9 to 16: Rock Creek Parkway, out and back

Rock Creek and Potomac Parkway is an out and back under trees, with the turn at km 12.15. Runners pass under the Dumbarton Bridge twice, at km 10.47 on the way out and km 13.79 on the way back, and meet the faster runners coming the other way. It is level, a stretch to settle into a rhythm before the monuments.

Km 16 to 25: the Lincoln Memorial and Hains Point

Ohio Drive brings the course past the Lincoln Memorial at about km 16.8, beside the gilded Arts of War sculptures at the end of Arlington Memorial Bridge. The organiser sends spectators here because they see runners twice, at mile 10 and again at mile 16. A short turn on Independence Avenue and West Basin Drive leads back to Ohio Drive and south into East Potomac Park.

Halfway falls on Ohio Drive, and the course rounds Hains Point at km 21.4, its lowest ground at about 1 m above sea level. Along this stretch the organiser places the Wear Blue Mile, “along Haines Point at mile 12”: posters of fallen service members, each with a photograph and a name, and beside each one an American flag held by a volunteer, often fellow military or the families of the fallen. Ohio Drive then runs back north past the Jefferson Memorial at about km 24.3 to 15th Street.

Km 25 to 32: Independence Avenue and the Mall

An out and back on Independence Avenue, from about km 25.0 to 26.8, holds the first of the three gauntlets. In 2026 runners not through the DC Gauntlet by 12:33pm were diverted from the certified course at Independence Avenue to 14th Street.

Then comes the Mall. 15th Street leads to Madison Drive on the north side at about km 27, and the course runs east to the Capitol end, turning there at mile 18 (about km 29). Jefferson Drive brings it back west along the south side, past the Smithsonian Castle at km 30.3, to 14th Street at km 30.8. The Mall is flat, between about 3 m and 7 m above sea level.

Km 32 to 34: Beat the Bridge

The best-known line of the race is a clock, not a hill. Every runner must reach the intersection of 14th and D Streets, before the 14th Street Bridge, by 1:15pm at mile 20 (km 32.2): the Beat the Bridge Gauntlet, 5 hours 55 minutes after the 7:20am start in 2026. The course is on the bridge from about km 32.1 to 33.0, where a self-serve water station stands, and follows the HOV lanes and the I-395 express-lane ramp back into Virginia to about km 34.2.

Km 34 to 40: the Pentagon and Crystal City

Back in Arlington, the course loops by the Pentagon on South Eads Street and the access roads, then takes Army Navy Drive and 12th Street South into Crystal City at about km 35.8. Crystal Drive is another out and back, turning at about km 36.7. The third gauntlet sits where 12th Street South becomes Crystal Drive: in 2026 it closed at 1:49pm, with the same diversion and the same loss of an official finish. Long Bridge Drive and North Boundary Drive lead past the Pentagon again at about km 39.8.

Km 40 to the finish: the hill to the memorial

The course rejoins Route 110 at about km 40.8 and runs north, past the Memorial Avenue gate of Arlington National Cemetery at about km 41.5, to Marshall Drive at km 42.06. The organiser calls it an uphill finish, and it is a short one: the ground under the last 650 m rises about 14 m. The line is on Marshall Drive below the Marine Corps War Memorial, where the race has finished since 1976.

The organiser had not published 2027 race week details when this was checked, so everything below is how the 2026 race ran. The 2026 race-week pages no longer load on the organiser’s site, and no 2027 pages had replaced them.

Expo and bib pick-up

In 2026 the Health and Fitness Expo was at the Building Museum, from 12 noon to 6pm on Wednesday 21 October and from 10am to 6pm on Thursday 22 to Saturday 24 October. Pick-up ran by time slot, chosen in advance through a link the organiser sent to registered runners. Runners brought the e-Card and a photo ID, and collected the bib, the timing device and the technical shirt. There was no pick-up on race morning, except for runners who had bought Race Day Packet Pick-Up.

On the Saturday the MCM 8K started at 7:20am in West Potomac Park, followed by the MCM Kids Run for children aged 5 to 12, over 0.8 km, with four start times between 9am and 10am.

Race morning, bags and corrals

Metro opened at 5am on race day, and the organiser warned that a weekend wait for a train could be up to 15 minutes. Runners took Metro to Pentagon or Pentagon City for the Runners Village in the North Pentagon Parking Lot, and were screened on arrival at the start and finish areas.

Bags went to the UPS trucks in the Runners Village, in the clear plastic bag handed out at packet pick-up with the sticker from the back of the bib. The trucks are organised by event and bib number. The organiser publishes no closing time, which is a reason to drop the bag early.

The opening ceremony began at 7am: the March on Colors and the national anthem, then howitzer blasts to mark the start. The wheels start, for wheelchair and handcycle athletes, was at 7:05am, duos at 7:07am and all runners at 7:20am. New in 2026, runners lined up in corrals by expected finish time.

On the course and at the finish

The 2026 race-day page listed 12 water points, 10 aid stations and three gel stations, one of them approaching mile 14, plus the self-serve water on the 14th Street Bridge. The organiser’s required pace is 14 minutes per mile, and the gauntlets above are what enforce it.

Bags came back at the Finish Festival in downtown Rosslyn, at Wilson Boulevard and North Lynn Street, which ran from 8am to 4pm. Spectators were kept off the start and finish lines in 2026, so the festival is the place to meet.
