2018 Marine Corps Marathon (Flickr pool photo by Kevin Wolf)

This weekend Arlington will host one of the world’s largest marathons, drawing around 30,000 runners.

But the influx of athletes also means residents should prepare for road closures, whether they are driving, biking or scooting.

Next Sunday, Oct. 29 participants in the 48th annual Marine Corps Marathon will gather along Route 110 between Arlington National Cemetery and the Pentagon. The MCM 50K race starts at 7:15 a.m., followed by the wheelchair/hand cycle division at 7:50 a.m. and the marathon at 7:55 a.m.

Runners will “tour the nation’s most recognizable landmarks while being supported by the men and women of the United States Marine Corps,” the race website says.

Road closures will affect parts of Arlington, including I-395 between Rosslyn and Crystal City, from 3 a.m. to 6 p.m., according to an ACPD press release.

Viewing locations for spectators locally include the starting line in Arlington, the first mile in Rosslyn, Crystal Drive in Crystal City and the finish line near the Marine Corps War Memorial.

Friends and family can track runners in real-time via text, email or social media.

After crossing the finish line, runners and spectators can head to the Finish Festival in Rosslyn at the intersection of Wilson Blvd and N. Lynn Street. The festival will run from 8 a.m. to 4 p.m. and feature beer, food, live music and giveaways.

The Runner’s Village is located in the Pentagon North Parking Lot C, accessible via the Pentagon and Pentagon City Metro stations, which open at 5 a.m., ACPD says.

A shuttle service will operate between the Runner’s Village and the Fashion Centre at Pentagon City. There will be free parking in the underground lot at 23rd Street S. and Crystal Drive, according the race website.

Runners and spectators can expect security screenings for prohibited items, including pets, drones and alcohol, at the start and finish areas.

Registration is still open for the 10K and 50K races, as well as the mile-long kids run on Saturday, Oct. 28. The kids run, open to children ages 5-12, is set to take place at the North Pentagon Parking Lot from 9:20-11:40 a.m.

Below is the list of planned road closures, per an ACPD press release.

Arlington County police are investigating shots fired in the Green Valley neighborhood.

The gunfire rang out around 10 p.m. Friday night near The Shelton apartment complex. No injuries were reported but a bullet damaged a window in a nearby residential building.

More, below, from an ACPD crime report.

SHOTS FIRED, 2025-10100198, 3200 block of 24th Street S. At approximately 10:01 p.m. on October 10, police were dispatched to the report of possible shots heard in the area. During the course of the investigation, officers recovered evidence confirming shots had been fired in the area and property damage to the window of a residential building was located. No injuries were reported. There are no suspect(s) descriptions. The investigation is ongoing.

The same block was the scene of a shooting in November 2024. The teen victim of that shooting survived his serious injuries.

Long-range weather outlooks are predicting an overall milder winter with more precipitation — which may or may not include more snow.

The National Weather Service and Old Farmer’s Almanac recently released their winter outlooks and there’s hope for Arlington snow lovers — though another rainy, snow-starved winter remains a possibility.

NWS is predicting above average precipitation and above average temperatures for the D.C. area., though the confidence for both is below 50%.

The Farmer’s Almanac, meanwhile, agrees that it will be an overall milder winter, but thinks that a colder start to 2024 will bring more snow than usual. From its Atlantic Corridor forecast:

Winter precipitation and snowfall will be above normal (2 to 3 inches above monthly averages). The snowiest periods will occur at the end of December, late January, and mid-February. We don’t expect a white Christmas. […]

Winter temperatures will be above normal overall. Specifically, December is slightly above average temps; temperatures for January and February are below average. The coldest spell will run from late January into mid-February.

Making the forecast tricky for meteorologists is the expected presence of El Niño, the atmospheric phenomenon linked to warm ocean temperatures in the Pacific.

The Washington Post’s Capital Weather Gang notes that while some El Niño winters end up as snow busts, others bring blizzards.

One recent forecast called for the current El Niño to become a “super” El Niño this winter. Super El Niños are those that produce the most intense ocean warming and often the most extreme weather impacts worldwide.

“Washington’s least snowy winters — 1997-1998 and 1972-1973 — both came during super El Niños,” added Capital Weather Gang’s Ian Livingston. “A similar strength event in 2015-2016 was mainly snowless, but punctuated by a historic blizzard in January.”

After a weak season for snow last year — and below-average snowfall six of the past seven years — ARLnow readers say they’re ready for a winter wonderland. Some 62% of respondents to our poll last month said “bring on the snow” when asked about the prospect of a big winter storm.

The Capital Weather Gang and local TV stations typically release their Washington winter outlooks around mid-November.


Announcement

Divorce is difficult both emotionally and logistically. Divorce Mediation assists couples in untangling their life while reducing the elevated stress of the process. The mediator will help divorcing couples through the process in a few short sessions creating a solid foundation of understanding on which each can construct their independent new destiny.

The legal complexities of divorce, as well as the vagueness of the required legal conditions, are difficult enough without having to arrange a new independent life at the same time. While many partnerships end after a divorce decree is issued by the court, many others continue, especially if children are involved.
