As mapped, the run begins from the center of town, near the base of Town Lift. You can access it from other points, however, including the trailhead parking area at the south end of Main Street. It begins as a dirt road but soon turns to singletrack. You’ll start uphill right away, and the grade doesn’t lessen much until you reach the top. The trail has plenty of roots and rocks to keep things interesting, but for the most part, the surface is firm dirt. You’ll likely share it with mountain bikers, most of them riding in the downhill direction, but it’s not an especially high-traffic trail.

The lower section tends to be sunny and warm, with well-spaced trees and some open ski runs. Soon enough, you’ll enter a dense stand of aspen, and stay there pretty much all the way to the top. Sweeney’s feeds into John’s Trail (intersections are well marked), and John’s ends at the top of Bonanza Lift, in a clearing that gives quite a good view.

You’ll notice this mini-summit is nowhere near the top of the mountain, so you can keep running upward on other trails if you still have it in you. The historic Silver King Mine is just over the hill from this spot, so with a slight detour, you can see an impressive relic of Park City’s past. When you’re ready to go down, return the way you came (mapped) or make a loop with the ski run that follows the ridgeline.
