You have probably run past the gate. Somewhere along the southern edge of the neighborhood, a trail that looked exactly like the one before it suddenly required a card you may or may not be carrying. If you have ever wondered why one stretch of dirt path in the Backcountry Wilderness Area felt open to everyone and the next felt like it belonged to someone else, the answer is simpler than it seems: it does belong to someone else, and knowing where that line falls changes how you should plan your fall running season.
The Backcountry Wilderness Area covers roughly 8,200 acres on the south end of Highlands Ranch, and on a map it reads as one continuous block of open space. On the ground, it is two separate trail systems stitched together, each with its own rules about who gets to use it, whether a dog can come along, and what time of year it is even open. That distinction is not trivia. It is the reason the neighborhood's marquee running event, the HRCA Backcountry Wilderness Half Marathon, routes its entire 13.1 miles on only one half of that acreage.
The Race Route Tells You Something
The 18th Annual Backcountry Wilderness Half Marathon returns to Highlands Ranch on Saturday, November 7, 2026, starting at 9 a.m. It is a single-loop course, 100 percent dirt, gravel, and singletrack, and it runs entirely along the Douglas County East/West Regional Trail as it cuts through the wilderness area. Runners cross Grigs Road early in the course and again on the way back toward the finish, with an aid station and cutoff checkpoint at the Grigs Road Pavilion around mile 8.9.
What the race does not touch is the Wildcat Mountain and Highlands Point trail systems, the roughly 11.2 miles of natural surface trail inside the same Backcountry acreage that belong to the Highlands Ranch Community Association rather than the county. Those trails are reserved for HRCA members and their accompanied guests. A half marathon field drawing hundreds of registrants, many of them visitors from outside the neighborhood, has no legal way to send that field down a membership-only trail. So the county trail becomes the only option, and the route reflects an access boundary most spectators would never notice.
A few practical details for anyone considering the race or just watching from the sidelines this November:
- Cash prizes go to the top three finishers in male, female, and non-binary categories: $600 for first, $400 for second, $200 for third.
- Dogs and strollers are not permitted on course, a rule tied to wildlife protection along the route rather than race logistics.
- Finishers are fed a pancake breakfast from Flippin' Flapjacks and handed a post-race beer courtesy of Living the Dream Brewing, a detail that tells you as much about the neighborhood's running culture as any mileage figure does.
One Wilderness Area, Two Rulebooks
The split between the public county trail and the private HRCA trails is not a technicality that only matters to race directors. It shapes how residents actually use the Backcountry day to day. If you own a home in Highlands Ranch and carry an HRCA membership card, you already have access to the Wildcat Mountain and Highlands Point systems. If you are hosting a friend from out of town, that friend needs to be with you to use those same trails legally. The Douglas County East/West Regional Trail, by contrast, is open to anyone, resident or not, membership card or none.
Dog owners run into this most often. Dogs are prohibited on the Wildcat Mountain and Highlands Point trails, with one narrow exception at Rocky Gulch, where leashed dogs are allowed. If your evening routine involves a dog and a trail, and you have found yourself turned back or second-guessing a route, the Backcountry's private trails are the likely culprit. Highland Heritage Regional Park runs an off-leash area called Hound Hill that the Metro District manages specifically for this reason. It is a different park entirely, but it exists partly because the Backcountry's own trail rules leave a gap for dog owners to fill somewhere else.
Why Wildcat Mountain Goes Quiet Every Winter
There is a second layer to this that matters if you are planning training runs into the colder months. The private HRCA trails, specifically the Wildcat Mountain system, close annually from January 1 through March 31 for eagle nesting, and individual trails inside that system can stay closed longer depending on how the season plays out. The public Douglas County trail is not subject to that closure, which is part of why the November half marathon can be scheduled with confidence on its current route while a spring race on the same acreage would face a very different set of constraints.
For residents building a running calendar around the Backcountry, this closure window is worth marking now, before the half marathon even happens. A route that works in September and October may not be available in January, not because of snow or mud, but because a specific trail system is protecting nesting golden eagles on a schedule that has nothing to do with weather.
How the Local Running Club Trains Around All of This
The Highlands Ranch Running Club has built its entire training calendar with these boundaries in mind. The club runs twice weekly, with Wednesday track workouts from March through October at 6:30 p.m. and Saturday long runs that continue year-round, all under the direction of Coach Claire Gyomory. Membership includes official Road Runners Club of America benefits along with a small but telling local perk: a dollar off beers at Living the Dream Brewery after Wednesday club runs, the same brewery that pours the post-race beer at the half marathon in November.
The club's published long-run routes read like a tour of the trail systems this piece has been describing. Daniels Park offers a hillier loop with varied terrain. The High Line Canal gives a flat, scenic option with multiple access points so distance can flex up or down. A route from the Westridge neighborhood leads directly into the Backcountry, and other club routes push out to riverside miles along the South Platte, a reservoir loop with mountain views, and a canyon out-and-back where regulars keep an eye out for bighorn sheep. None of these routes require guessing which trail system you are on, because the club has already mapped where public access ends and membership access begins.
What This Actually Means If You Live Here
None of this changes whether Highlands Ranch is a good place to run. It is. What it changes is how you plan around it. If you are training for the November half marathon, you already know the entire course sits on public land, so registration and access are never in question. If you are building your own fall routine through the Backcountry on trails outside race day, your HRCA membership status determines what is actually available to you, your dog's access depends on which trail you pick, and your winter options narrow starting January 1 regardless of how the weather looks.
The wilderness area was never one trail system pretending to be simple. It is two systems, county and community association, running side by side on the same acreage, and the neighborhood's biggest running event exists on the half of it that belongs to everyone.
If you are weighing a move to Highlands Ranch and trail access is part of what draws you here, it helps to talk through which pocket of the neighborhood puts you closest to the trails you would actually use, membership rules included.
