This is the longest cross country riding loop, 100% singletrack, right in the City of Fitchburg and easily accessed by Madison residents.
The trails are quickly evolving with lots of new trail added in 2013 and more to come in 2014 and beyond. There is a new climb along the west side that takes you to the top and a whole bunch of twisty stuff along the bottom near the lake. These new additions make this trail system much more family friendly and fun for everyone. If you haven't visited Quarry Ridge in 2013, come check it out and take note of the new trails.
The trail starts winding through a flat area testing your skills at cornering. The Sandy Climb
uphill is challenging for many riders. Once on the top, take the long, flowing, and fun downhill to the bottom. Take a left at the bottom and ride the new uphill back to the top, then redo the long downhill. Repeat this loop several times for additional miles.
The route requires repeating the long downhill, but it allows a 2.6 mile loop for cross country riding. It's a good distance to session and practice your cornering, climbing, and downhill skills.
There is a parking lot off of Fitchrona road with a short paved trail to the entrance. Alternately, ride the Military Ridge Trail (State Trail Pass required) and avoid driving.
Quarry Ridge consists of a main loop (about 1.5 miles) as well as several downhill lines of various difficulty. The main loop is accessed by taking a 2-way trail across the field. Once you cross the field and a small gulley, the trail is a straight shot along the base of the ridge. It eventually turns riders up a sandy climb to the high point, then follows the gradually descending ridgeline back to the start of the loop. The singletrack on the main loop is fast and has some sections of very nice flow with only 1 technical section to trip up beginners. More advanced riders can challenge themselves to power through the steep sandy climb, slice through the long downhill with as little brakes as possible, and try to beat their own times on each successive loop. A new uphill is an easier way back to the top to enjoy the downhill.
If you want to mix things up or ride something more technical, look for the alternate lines which cut down the face of the ridge. These lines are accessed by bearing right on any of the forks in the trail at the top of the hill. These lines have moderate to difficult jumps and features.
