Pull into the Sparks Road lot on a normal Saturday morning in October and you'll find space. A few cars, a dog walker circling back toward the iron bridge, maybe a cyclist refilling a water bottle at the fountain by the old Sparks Bank building. Drive seven miles north to Monkton during either of the two running-event weekends this fall and that same kind of lot looks nothing like itself. Cars line the shoulder of Monkton Road. The station platform has a line for the bathroom. Someone is selling water out of a cooler. Garden Glow brings a different kind of congestion: evening road traffic on nearby Jarrettsville Pike.
Those three weekends aren't random, and they aren't spread evenly across the trail's twenty miles. The two running events on the Torrey C. Brown Rail Trail this fall bring runners through Monkton; Garden Glow brings separate evening road traffic to nearby Jarrettsville Pike. The rest of the corridor, including the mile markers where most locals actually walk their dogs or ride after work, barely notices any of it.
Three Different Organizers, One Village
The Charm City Run 20-Miler kicks off the season on Sunday, September 27. It's built as a training race for runners chasing fall marathons in Baltimore, Chicago, Richmond, and beyond, and the course description leans on one detail above the rest: indoor restrooms at Monkton Station, a rarity on a trail otherwise served by port-a-pots. That single amenity tells you where the race routes its runners.
Three weeks later, on the evenings of October 15 through 18, Ladew Topiary Gardens runs Garden Glow, its Halloween lighting event, from 5 to 9 p.m. Ladew sits at 3535 Jarrettsville Pike, a few minutes off the trail on the Monkton side, and the garden's regular public season closes for the year on October 31. Garden Glow is one of the last reasons cars will be turning onto Jarrettsville Pike after dark this year, and it draws a crowd that has nothing to do with running.
Then, on Saturday, November 28, the Saturday after Thanksgiving, the NCR Marathon and Half return for their 37th year. It's the oldest continuously running USATF-certified marathon in Baltimore, and it starts not in Monkton but at Oldfields School in Sparks-Glencoe, sending runners downhill on Glencoe Road before they turn onto the trail for an out-and-back course along Big Gunpowder Falls. Runners who've done it before know the trick: Monkton is still the spot to stop for a real bathroom partway through the course, according to race reviews on the event's own registration page. The start line is in Sparks-Glencoe. The relief stop, and a good chunk of the foot traffic, is still Monkton.
Here's the calendar in one place:
| Event | Date | Where It Touches the Trail |
|---|---|---|
| Charm City Run 20-Miler | Sunday, September 27, 2026 | Uses Monkton Station's indoor restrooms along the course |
| Ladew Garden Glow | October 15-18, 2026, 5-9 p.m. | Ladew Topiary Gardens, off Jarrettsville Pike near Monkton |
| NCR Marathon & Half | Saturday, November 28, 2026 | Starts at Oldfields School, Sparks-Glencoe; runners route through Monkton mid-course |
Three organizers with nothing to do with each other. Two bring runners through Monkton; the third brings evening road traffic nearby.
What Each One Actually Changes
None of these events shuts the trail down. The 20-Miler and the marathon both use the trail itself, not the roads around it, so a Sunday dog walk in late September or late November is still possible, just crowded with runners for a few hours. What changes is parking and bathroom access at Monkton specifically. The station's indoor restrooms exist because Monkton Station has historically kept limited public hours, open weekends in spring and fall according to Maryland's own trail page for the route, and race organizers plan their courses around that scarcity rather than around it being unlimited.
Garden Glow is the one event on this list that isn't on the trail at all. It's a ticketed evening event at Ladew, and the traffic it generates is road traffic on Jarrettsville Pike and the surrounding lanes into Monkton, not trail traffic. If you live along that stretch, the four nights in mid-October are worth planning around even though you'll never see a runner.
The Stretch That Doesn't Move
Compare all of that to the Sparks Bank Nature Center, sitting at mile 3.8 on the trail in a building that's been standing since 1916. Gunpowder Riverkeeper has run the center since 2023, and its schedule doesn't shift for race season or garden events. It's staffed by volunteers, open on weekends when someone is available, and its fall programming, like evening Owl Prowl hikes, runs on its own volunteer-dependent clock regardless of what's happening seven miles north.
The same goes for landmarks further out on the trail, like the small hill north of Hunt Valley locals know for its scattered garden gnomes. None of that stretch sees a bump from any of the three fall events. If your daily walk or ride keeps you south of Sparks or well north past Monkton toward White Hall or Parkton, this whole fall calendar is mostly background noise you'll read about rather than experience.
Reading Your Own Fall Weekend
If you live closer to Sparks or points south, your one weekend to plan around is November 28, and even then it's a Saturday morning event, not an all-weekend closure. If Monkton is your regular stop for coffee, the trail's tube and bike rental shop, or just the easiest place to park, you've got three event windows to keep in mind: late September and late November for trail crowds, and the four nights of Garden Glow in mid-October for evening road traffic nearby. Everywhere else on the twenty miles between Ashland and the Pennsylvania line, the trail keeps doing what it does the rest of the year, which is mostly nothing dramatic at all.
That's worth knowing not because any of it is a problem. It's the kind of pattern you only notice after a few falls of living along this corridor, when you start recognizing that the trail's rhythm isn't governed by the calendar so much as by which half-mile of it the two running events happen to need, while Garden Glow brings separate evening road traffic nearby.
If you're already living along the NCR corridor and curious what a property near Monkton, Sparks, or further out toward the Hereford Zone is actually worth in today's market, or if you're thinking about what it would take to sell land or a home out this way, the Dustin Prievo team knows this stretch of Baltimore County from the ground up.
