Arlington doesn't run on one calendar this fall. It runs on several, stacked on top of each other and finishing at different times. The Wednesday market in Rosslyn and the Saturday market at Metropolitan Park both pack up for the season by the end of October. The Saturday market in Courthouse and the Sunday market on Columbia Pike don't pack up at all. They run straight through the winter, just with shorter hours. Layer in a jazz festival with a fixed date, a restaurant week bounded by a hard start and end date, and a play that closes November 1, and what looks like a loose season of neighborhood happenings turns out to be a set of deadlines, most of them landing in the same eight weeks.

The trail that connects all of it has a name, and knowing it changes how you spend a Saturday.

One Loop, Five Neighborhoods

Bike Arlington calls it the Arlington Loop: the Mount Vernon Trail, the Custis Trail, the W&OD Trail, and the Four Mile Run Trail, joined into a single paved circuit that runs about 16 miles and stays separated from car traffic except for a handful of street crossings. It has access points in Bluemont, Rosslyn, Crystal City, Shirlington, and Columbia Pike, which means five neighborhoods that residents usually think of as separate destinations are, geographically, one continuous ride.

The Custis Trail is the connector most people already know without knowing its name. It parallels I-66 out of Rosslyn, climbs enough hills that regular riders warn newcomers about it, and starts at a small landmark most Rosslyn residents pass without noticing: the Bike-o-Meter at North Lynn Street, where the trail crosses into the neighborhood. The W&OD Trail, on the other end of the Loop, doesn't reach into downtown Washington at all. It stops in Shirlington, roughly six miles from the city by bike, which makes Shirlington less of a random stop on the map and more of an actual endpoint, a place the trail was built to end at.

That matters this fall because Shirlington is also where the county's biggest closing-night deadline is sitting.

The Markets on a Clock, and the Ones That Aren't

Here's the split, market by market, based on the posted schedules for this year:

If your regular market is the Rosslyn Wednesday stop or the Saturday setup at Metropolitan Park, this fall is your last full run of it until spring. If you shop at Courthouse, Cherrydale, Westover, or Columbia Pike, nothing changes for you except the sun setting earlier.

The Courthouse market is worth a second look regardless of season. FreshFarm, which runs it, has said the market turns away more than 60 vendor applicants every year and expanded its physical footprint this season to make room for more permanent stalls. That's not a small neighborhood pop-up being generous with its calendar. It's an institution operating at a scale the seasonal markets aren't built for, which is part of why it doesn't need a winter break the way a folding-table setup at a park does.

Three Fixed Dates Between Now and Winter

The market schedule is the background rhythm. Three dates sit on top of it, and none of them repeat if you miss them.

September 12 is Rosslyn Jazz Fest at Gateway Park, one of the neighborhood's annual outdoor music fixtures and the easiest of the three dates to combine with a Loop ride, since Gateway Park sits close enough to the Custis Trail entrance to make it a natural stop rather than a special trip.

October 12 through October 19 is Arlington's fall Restaurant Week, run by the Arlington Chamber of Commerce. It's the second Arlington restaurant week of the year. The first ran in late August with 15 participating restaurants offering fixed-price menus, including Locket in Rosslyn, known for its patio and contemporary American menu, and SER in Ballston, the family-owned Spanish spot on North Glebe Road. Both sit directly on the Loop route. The October lineup hadn't posted as of this writing, but if the pattern holds, expect a similar mix of Loop-adjacent kitchens rather than an entirely new set of names.

November 1 is closing night for Signature Theatre's run of "Merrily We Roll Along" in Shirlington, on stage since late August. Shirlington isn't an arbitrary location for a theater. It's the western anchor of the W&OD Trail, the same trail that starts, on the other end, at the Rosslyn Wednesday market.

Stringing It Together Before the Loop Goes Quiet

None of this requires four separate trips. A weekend built around the Loop can cover most of it in far less driving than the calendar suggests:

• Saturday, September 12: start at the EatLoCo market in Metropolitan Park, then take the Mount Vernon Trail north into the Custis Trail and end the ride at Gateway Park for the Jazz Fest, which starts at 1 p.m.
• Any Wednesday through the end of October: swing by the Rosslyn FRESHFARM market before it closes for the season, since it won't reopen until spring.
• The week of October 12 to 19: pick a Restaurant Week stop along the route, whether that ends up being Locket, SER, or whichever kitchens confirm for the fall round.
• Before November 1: catch a performance of "Merrily We Roll Along" in Shirlington, at the point where the trail itself runs out.

Do all four and you've covered five neighborhoods on one continuous paved route, timed to a set of deadlines that don't come back around until next year.

Arlington's fall calendar rewards people who already know the county well enough to plan around it, which is exactly the kind of local read that comes from paying attention to a place rather than just passing through it.
