Marine Corps Marathon: you are screened at both ends, and your bag finishes in a different neighbourhood

Three places, not two

Most point-to-point races ask you to solve a start and a finish. The Marine Corps Marathon has a third fixed point, and it is the one that catches people.

We geocoded all of them:

Leg	Distance
Runners Village (North Pentagon lot) → Marine Corps War Memorial	2.53 km
Finish → Rosslyn baggage trucks and Finish Festival	0.67 km

You start at the Pentagon. You finish at the Iwo Jima memorial. And your bag — dropped at UPS trucks in Runners Village before the start — is waiting a further 670 metres away, in Rosslyn, at the corner of Wilson Boulevard and North Lynn Street, where the Finish Festival is held.

So the day ends with an extra walk that most people have not planned for, taken after 26.2 miles and a climb to the memorial, before you can get to dry clothes.

Set the zones against those points and the answer falls out:

Zone	To the start	To the finish & bag
Rosslyn	3.19 km	0.67 km
Pentagon City	1.02 km	3.28 km
Crystal City	1.62 km	4.11 km
Washington DC (Mall side)	3.46 km	4.04 km

Nothing walks to the start. Pentagon City comes closest at a kilometre, but a Pentagon City base leaves you three and a quarter kilometres from your bag at the end of the day, having already walked from the memorial to Rosslyn to get it.

Rosslyn is the answer, and the reasoning is the same principle this site applies everywhere: when you cannot remove a journey, put it at the end of the day rather than the beginning. Rosslyn Metro reaches the Pentagon start in two stops on a morning with no deadline other than a 07:20 gun; and when you finish, your bag, the festival and your room are all within about seven hundred metres.

Everyone is screened, at both ends

The organiser’s wording is short and worth reading twice:

All runners and spectators will be screened upon arrival to the start and finish areas on event morning.

Not just runners. Not just the start. This is a race organised by the US Marine Corps around the Pentagon, and the security posture reflects that.

It puts MCM in the same category as Philadelphia, where the perimeter rather than the distance is what governs the morning. The practical differences from a normal marathon:

• Arrive earlier than the gun time implies. A 07:20 start with screening in front of it is not a 07:00 arrival.
• Your supporters are screened too, so a family planning to see you off needs the same margin you do.
• Carry as little as possible. The clear bag issued at packet pickup is the only bag that goes on the truck anyway.

A Rosslyn base helps here as well, because the Metro delivers you into the start area rather than leaving you to find parking near the Pentagon on a morning when the roads around it are closing.

The pace rule is not a finish-line cut-off

Most races give you a time limit at the finish. MCM does something stricter, and the organiser states it in one line: the required pace is 14 minutes per mile, and you must make the gauntlets.

Gauntlets are marked points on the course that you have to reach by a given time. Miss one and your race ends there, mid-course, rather than at a finish line you were slowly approaching. The positions are on the official course map, and they are worth looking at before race day rather than discovering on it.

Fourteen minutes per mile is a little over six hours for the full distance, which is generous by most standards. The difference is where it bites: a slow first half cannot be recovered later, because the checkpoint arrives before the finish does.

Arlington is a small market hosting a very large race

MCM is the third-largest marathon in the United States. Arlington is not a large hotel city. That combination shows up clearly in the numbers.

Checked on 4 August 2026, twelve weeks out, comparing race weekend against an ordinary weekend the week before:

	Race weekend 23–26 Oct 2026	Control 16–19 Oct 2026
Properties in Arlington	93	150

Sixty-two per cent remaining. And on price, for the three properties we could match across both searches:

Property	Race weekend	Control	Multiple
Hilton Garden Inn Arlington/Courthouse	$1,810	$521	3.47×
Sonesta Select Arlington Rosslyn	$1,159	$450	2.58×
Clarion Collection Arlington Court Suites	$827	$397	2.08×

Median 2.58×, with one hotel at three and a half times its ordinary rate. Only three matched pairs were visible, so treat the precise figure with more caution than Chicago’s six-unit comparison, but the direction is unambiguous, and it is one of the sharper premiums we have recorded.

There is a straightforward reason to look across the river. Washington DC has far deeper supply than Arlington, and the Metro connects both ends of the race. The cost is that DC is the furthest option from both the start and the finish, and you cross the Potomac twice on a day when the bridges are part of the course.

No deferrals, no transfers

One policy line that changes how you should book:

There are no deferrals and no transfers of registration.

For a race that draws runners from across the country and beyond, that removes every option if something goes wrong. You cannot move your entry to next year, and you cannot pass it to someone else.

The entry risk is therefore unmanageable. The accommodation risk is not, and given a market at 62 per cent supply and 2.5× prices, a refundable rate is worth proportionally more here than at a race where rooms are cheap and plentiful.

The course crosses the river twice, which decides your supporters’ day

MCM is run in two jurisdictions, and understanding the shape of it is what lets anyone watching you plan a sane morning.

You start in Virginia, at the Pentagon. The course crosses the Potomac into Washington DC early, runs up through Georgetown, the organiser’s Water Point 2 sits at M and 33rd Streets — then along Rock Creek and Potomac Parkway, out around West and East Potomac Park and Hains Point, back through the National Mall past the Smithsonian and the Department of Agriculture, and then crosses the river again on the 14th Street Bridge into Crystal City before climbing to the memorial in Arlington.

Two consequences follow.

For you: the two river crossings are the pinch points, and the 14th Street Bridge, where the organiser puts a self-serve cupless water station, arrives late, around the point where the race stops being enjoyable. It is long, exposed and quiet.

For anyone supporting you: the course passes through more genuinely interesting places than almost any marathon, but the crossings make it hard to see you twice. The workable pattern is the Mall in the middle of the race and then Rosslyn at the end, which is another argument for a Rosslyn base — supporters can walk from the Mall viewing to the finish festival without having to cross a closed bridge.

The one part of the course worth planning to be near, if you are not running, is Hains Point at mile 12. That is the wear blue Mile: Faces of the Fallen posters, each with a photograph and a name, and an American flag draped with a black ribbon held by a volunteer — often serving military or the families of the fallen. The organiser calls it the iconic on-course experience of the MCM, and runners consistently describe it as the reason they came back. It is also, for what it is worth to a first-timer, positioned at exactly the point in a marathon where a reason to keep going is most useful.

A note on why this page exists now

This guide was blocked for most of the project. Our own records had the Marine Corps Marathon failing the five-source standard because the organiser had not published participant logistics for the edition in question.

Re-checked twelve weeks before the 2026 race, that is no longer true. The organiser now publishes start times, the Runners Village location and its Metro access, the screening policy, the full baggage chain including the Rosslyn collection point, twelve water points and ten aid stations by position, the pace requirement, and the entry rules. It clears the bar comfortably.

The lesson is worth recording for the races still waiting: a blocked guide is usually blocked by the calendar rather than by the organiser, and the fix is to check again closer to the edition rather than to write around the gap.

What we cannot tell you yet

Arlington County had not published its 2026 road-closure and parking notice when we checked on 4 August 2026, so there are no street-level closure times on this page.

The gauntlet positions are on the official course map rather than stated as clock times in the participant text, so confirm yours against the map rather than assuming a uniform cut-off.

What is fixed: a 07:20 start at the Pentagon, screening for everyone at both ends, a finish 2.53 kilometres away at the memorial, a bag another 670 metres on in Rosslyn, fourteen minutes per mile enforced at checkpoints, and no way to defer or transfer if you cannot make it.
