The Marine Corps Marathon closes roads across two jurisdictions — Arlington County and Washington, DC — and the logistics of getting around on race weekend are as much a part of planning for MCM as your training block. The short version: this is a Metro race. Plan around the Washington Metropolitan Area Transit Authority's rail system, and race weekend gets dramatically simpler.
Why driving doesn't work on race day
MCM's course threads through the Pentagon, Rosslyn, Georgetown, the National Mall, and Crystal City, and road closures follow the runners — meaning closures ripple across the region for most of the morning and into the afternoon. Key Potomac River crossings, including the bridges the course itself uses, are closed to vehicle traffic for hours. Locals who don't plan around this find themselves stuck rather than simply inconvenienced, and runners who try to get dropped off near the start by car often end up walking further than if they'd taken transit in the first place.
Metro is the backbone of race day
On race morning, Metrorail typically opens earlier than its normal Sunday schedule specifically to move runners and spectators — exactly how much earlier varies from year to year, so check WMATA's race-week service announcements for the exact opening time. Trains still run at normal weekend frequencies rather than rush-hour frequency, so build in extra buffer time rather than assuming a train every few minutes. Fares are paid by tapping a SmarTrip card or a contactless debit/credit card at the gate — no need to buy a paper ticket in advance, though a one-day pass can simplify a day with multiple trips.
Getting to the start
Runners access Runners Village and the start corrals via the Pentagon or Pentagon City Metro stations, both served by the Blue and Yellow lines. If you're staying in Crystal City, MCM also runs its own shuttle service from the neighborhood directly to Runners Village on race morning — a good option if you'd rather avoid the Metro crowds entirely. Whichever way you go, build in more time than feels necessary; security screening and the walk from the station to the corrals both take longer than a typical race-morning routine.
Getting from the finish
The finish and the Finish Festival are both in Rosslyn, served by the Rosslyn Metro station on the Blue, Orange and Silver lines. MCM also runs return shuttles from the Finish Festival back to Crystal City for runners and spectators staying on that side of the course. Expect the Rosslyn station itself to be one of the most crowded points on the whole system in the hours after the race — a short walk to a neighboring station can sometimes beat waiting out the crowd at Rosslyn directly.
Flying in from out of town
Reagan National Airport (DCA) is the closest airport to the race, a short Metro ride from both Crystal City and Rosslyn on the Blue and Yellow lines. Dulles (IAD) is connected to the Metro system via the Silver Line, adding more travel time but avoiding the need for a rental car. Runners flying into BWI, further from the course, typically connect via MARC train or Amtrak into Union Station before transferring to Metro.
If you must drive
- Don't plan to drive directly to the start or finish. There is no runner drop-off at either location, and the roads around both are closed well before race time.
- Park at a Metro station outside the closure zone, ideally further out on the line you plan to ride in on, and take the train the rest of the way.
- Give yourself far more time than a normal Sunday for any drive that touches Arlington or downtown DC, even if your destination has nothing to do with the race.
- Check the official road-closure page close to race day. Exact streets and closure windows are finalized shortly before the event and can shift from year to year.
None of this is unique to MCM — most big-city marathons close roads — but the scale here is larger than most, since the course crosses between two separate jurisdictions. Build your race-weekend transportation plan around Metro first, and treat a car as a backup rather than the default.
MCM Metro guide: the backbone of race-day transportation
For most runners and spectators, the simplest Marine Corps Marathon transportation plan is built around Metro rather than driving. Search terms like “MCM Metro” are really shorthand for the same race-day strategy: choose lodging and meeting points around rail access, then use the system to reach the start area and leave the finish area while road closures are in effect.
Choose how you will reach Runners Village
For the 2026 race, the organizer lists Pentagon station on the Blue and Yellow lines as the access point for Runners Village. Its travel page also lists a Crystal City shuttle to the Pentagon North Parking Lot, running from 4:30 to 6:30 a.m. from 23rd Street and Crystal Drive. Choose one plan in advance, check the current departure and screening instructions, and leave enough time for the walk from transit to the village and your assigned start area.
| Option | Useful when | Check before race morning |
|---|---|---|
| Metrorail to Pentagon | You are staying near a station or want a direct rail approach. | The 2026 opening time is listed as 5 a.m.; confirm service, station access, and your walking route. |
| Crystal City start shuttle | Your lodging or parking plan is in Crystal City and the shuttle fits your assigned schedule. | Exact boarding point, operating window, eligibility, and whether the shuttle is still running when you arrive. |
| Driving | You need a car for part of the trip. | Do not assume you can drive to the start or finish. Check official road closures and event parking well before race morning. |
Plan the finish trip before the start
The finish festival is in Rosslyn, near Rosslyn Metro. The organizer lists return shuttles from the finish festival at Oak Street and Wilson Boulevard to 23rd Street and Crystal Drive. Decide whether you will take rail or shuttle before the race, and arrange a specific reunion point with family or friends; the finish area and station can be crowded, and a tired runner may not want to improvise a long walk.
Spectator travel and road closures
Spectators should build their itinerary around rail stations close to the chosen course segment and use the current map to understand which side of the Potomac they need to reach. The organizer lists Smithsonian for the National Mall, Crystal City for miles 22–23, and Rosslyn for the finish festival; L'Enfant Plaza also serves the Mall area. Arlington Cemetery station is listed for later opening at 8:30 a.m. for the 2026 event. Do not assume you can cross the course or drive between viewing spots on your runner's schedule.
- Check live WMATA service and the event's transportation page shortly before travel; race-day service can differ from a normal Sunday.
- Use contactless payment or a ready-to-use SmarTrip option so fare setup does not delay your trip.
- If traveling with a runner, coordinate separately: their start plan and your spectator plan may use different stations and times.
- Use the official course map and closure notices for final street access, parking, and drop-off rules; do not rely on last year's closure map.
The 2026 Marine Corps Marathon is scheduled for October 25. Start times, shuttle windows, station access, and road closures are edition-specific. Recheck the organizer's current travel page, race-day information, and course map before setting a final itinerary.
