The 14th Street Bridge reopens to traffic at 1:15 p.m. on Sunday 25 October, with or without marathoners on it. The cutoff at Independence Avenue, three miles back, is 12:33 p.m. Forty-two minutes for three miles is 14:00 per mile, the pace the Marine Corps Marathon gives as its limit, and the only part of the course where the deadlines require it.
The 51st Marine Corps Marathon starts at 7:20 a.m. on Route 110, between the Pentagon and Arlington National Cemetery, and finishes uphill at the Marine Corps War Memorial in Arlington. The Marine Corps has organised it since 1976, when 1,018 people finished. In 2025, 30,191 did, a record that made it the third-largest marathon in the United States.
Entry is $240 and there is no prize money. Registrations for 2026 are final, with no transfers or deferrals. Packet pickup runs Wednesday 21 October through Saturday 24 October at the National Building Museum, in timed slots booked from the bib confirmation email. Nothing is handed out on race morning.
Three deadlines and no finish cutoff
The race FAQ sets the limit at "14 min per mile and must make gauntlets." Almost every page that ranks for this race prints the pace and drops the gauntlets, though the gauntlets are what take runners off the course.
The course map lists the three gauntlets as clock times. Runners must be through Independence Avenue by 12:33 p.m., past the 14th Street Bridge by 1:15 p.m., and through Crystal City by 1:49 p.m. All three count from the 7:20 a.m. gun, regardless of when you cross the start mat. The Marine Corps gives a mile marker only for the bridge; WTOP's 2019 reporting and Washingtonian place the other two.
| Gauntlet | Mile | Deadline | Average pace needed from the gun | Cushion for a 14:00/mi runner |
|---|---|---|---|---|
| DC Gauntlet, Independence Avenue | ~17 | 12:33 p.m. | 18:25 /mi | 75 min |
| Beat the Bridge, 14th and D Streets | 20 | 1:15 p.m. | 17:45 /mi | 75 min |
| Crystal City, at Crystal Drive | ~22 | 1:49 p.m. | 17:41 /mi | 81 min |
Miss one and you are diverted off the certified course. You can keep running, but you won't be recognised as an official finisher. Neither the map nor any other Marine Corps page gives a cutoff for the finish line.
The Red, Gold and Green waves all start on the 7:20 gun, and you can move back a wave but never forward. With 25 minutes to reach the mat, a pessimistic figure, the pace needed to make mile 17 drops to 16:56 per mile, leaving about 50 minutes of cushion.
Race directories list a seven-hour limit for this marathon, and race databases, 42cal's among them, list 6:10. The Marine Corps publishes neither. The 6:10 is 14:00 per mile over 26.2 miles, which comes to 6:07, rounded up. The seven hours date from the old 7:55 a.m. start, when they left a walkable margin. From a 7:20 gun they end at 2:20 p.m., and reaching the finish by then from the Crystal City cutoff at 1:49 p.m. would take 7:23 per mile over the last 4.2 miles.
Why the deadlines never move
Road closures begin at 3:30 a.m., and every road on the course is open again by 5 p.m. The gauntlets are commitments to reopen those roads on time, negotiated with the agencies that own them, and they stayed put when the start moved.
Archived race-day pages show a 7:55 a.m. gun through the 2024 season, and the 50th edition in 2025 went off at 7:20. The map listed 12:33, 1:15 and 1:49 p.m. throughout, and WTOP reported the same three times in 2019. The pace needed to reach mile 17 went from 16:21 per mile to 18:25, and the back of the field gained 35 minutes at each checkpoint.
Anyone still on the far side of the bridge when it reopens is bused to the Finish Festival in Rosslyn. At the 2015 race, Washingtonian counted four straggler buses near mile 22, at 15th Street and Crystal Drive, and reported hundreds of runners boarding them each year. The Marine Corps publishes no count of swept runners.
Miles 1 to 8: the climb out of Rosslyn
The gun fires eight minutes before sunrise, at roughly the coldest moment of the day. Reagan National's normals for 25 October run from 47.5 °F to 65.5 °F.
The elevation profile on the course map has the road rising from about 56 feet at the half-mile mark to about 227 feet at mile 2.4, a gain of 171 feet out of Rosslyn at an average grade of 1.7 percent. The last mile of the climb averages about 2.4 percent, the steepest ground on the course. The road is Langston Boulevard, renamed by Arlington in 2021 and labelled that way on the certified course map; the race-day page still uses Lee Highway.
From the top, the course drops roughly 185 feet down Spout Run to the Key Bridge by mile 4, and by mile 8 it runs flat along Rock Creek Parkway at about 70 feet. The day's hardest climbing falls inside the first 35 minutes, on fresh legs, in a packed field. A course difficulty analyzer scores a course on its total gain, which says nothing about where the climbing happens.
Miles 11 to 15: Hains Point
The four numbered spectator locations the Marine Corps lists are the Lincoln Memorial around miles 10 and 16, the National Mall at miles 17 to 19, the Crystal City Metro station, and Rosslyn at the Finish Festival. None covers miles 11 through 15.
Those miles loop around Hains Point, at the southern tip of East Potomac Park. The race directs spectators to Metro, and the park has no station and no access road outside the closed course. The National Park Service describes it as a flat peninsula of reclaimed land with water on three sides, where the Potomac, the Washington Channel and the Anacostia converge. The course hits its low point there, about 8 feet near mile 14.3, with no built shelter.
Mile 12, inside the loop, is the wear blue: run to remember Mile. Volunteers hold an American flag draped with a black ribbon for each fallen service member, beside Faces of the Fallen posters. The race calls it a sobering segment of the course.
USATF certified the course as DC25002LMJ along the shortest possible line, following every tangent. The Hains Point loop, an out-and-back on Rock Creek Parkway, a loop of the Mall and another along Crystal Drive keep the course turning, and most watches finish between 26.5 and 26.8 miles.
Miles 17 to 20: the Mall and the bridge
The deadlines allow 18:25 per mile to mile 17, a walking pace, and 17:00 from the bridge to Crystal City. Between the DC Gauntlet and the bridge, out along the Mall and down to 14th Street, they allow 14:00.
From Independence Avenue at 12:33 p.m., the bridge is three miles and 42 minutes away. Time lost in the start corral doesn't change those 42 minutes, because both ends are fixed clock times, and a future change to the gun wouldn't change them either. A pace calculator puts 14:00 per mile over the full distance at a 6:07 marathon. Reaching mile 17 by 12:33 p.m. takes 18:25.
Miles 20 to 26.2: Crystal City and the finish
Crystal City, often written up as the course's other dead zone, is one of the four official viewing locations and has its own Metro station. Fluid stations, a gel station near Long Bridge Park and a DJ at mile 23 line the same corridor.
The certified finish line sits 137 yards past Marshall Drive, on the Iwo Jima access road. USGS readings along that ramp rise about 35 feet over the last 0.2 miles, an average grade of about 3 percent and a fifth of the Rosslyn climb, 24 miles later. The plotted line on the published elevation chart is still rising when it runs off the right edge of the graphic.
At 3:30 pace, the race is over by 10:50 a.m., below the 65.5 °F normal high. From the Crystal City cutoff at 1:49 p.m., the finish comes after solar noon, near the day's high, at the end of nearly all of the day's warming. Slower runners can weigh that when choosing an autumn marathon.
