“An event put on by trail runners for trail runners.”— Tom Robson
Featured Race - May 11, 2019
Taking place on the trails and hills west of Fort Collins in Lory State Park and Horsetooth Mountain Park, the Quad Rock 25/50 will take you on a tour of the Fort Collins skyline, situated on the northeastern boundary of Colorados mighty Rocky Mountains. Look east from the courses high ridges and you'll see the Great Plains extending as far as the eye can see; look west and you'll take in the layered ridgelines and summits of Northern Colorados Rocky Mountain swell, dominated 30 miles away by a towering Longs Peak, the undisputed monarch of Colorados northern Front Range.
We aspire to not only offer a first class trail racing experience on a challenging, scenic, and impeccably marked course, but also a top-notch post-race experience that will leave your bellies full, your feet tapping and your mouths yapping.
The 25-mile loop will take you to the base of two of the more prominent granite outcroppings atop the West Ridge of the Fort Collins skyline by way of the Mill Creek drainage and the Spring Creek Valley. All told, you'll ascend a touch over 5,500 vertical feet on more than 23 miles of premium, gnarled-out singletrack connected by two miles of dirt road. Run the second loop in reverse for a full 50 miles and a net vertical gain in excess of 11,000 feet.
Hang around after your run for live music, barbequed goodness, awesome awards, and some mighty tall tales.
Thats how we roll in The Fort. Welcome!
Drop bags will be allowed at the Horsetooth Trailhead (Mile 10.3 and 39.5) and the Soldier Canyon finish (Mile 24.9 for the 50 milers). Horsetooth drop bags will not be returned to the finish area until after all 50 milers have cleared the station. If 25 milers need to leave earlier, they may drive to the aid station to pick up their bags.
All trails in the park are well marked and the route can be run with a map and the following detailed directions. Any runner should be able to follow the course markings but if you are familiar with the directions below and carry a map, you wonâ€™t have any trouble on race day.
Take the first left into the Arthurs horse trailer parking lot and head straight onto the east side of the South Valley Loop Trail. Immediately after crossing the park border, turn right onto the Nomad Trail. At the next junction, take another right onto the Sawmill Trail. Continue up Sawmill and take your first left onto the Stout Trail, which will roll south to the Towers service road. Turn right on Towers Road (dirt) and continue up the hill until you reach the aid station.
From the Towers Road aid station, turn left onto the Spring Creek Trail and follow it all the way down the Spring Creek Valley, making a left, and staying on the Spring Creek Trail, at a three-way intersection by the creek at the bottom.
Follow Spring Creek Trail for another half mile, after which the main trail will turn into the Horsetooth Falls Trail and will take you back to the Horsetooth Trailhead aid station, which is also the main parking area for the Horsetooth Mountain Open Space.
From the Horsetooth Trailhead, take the Soderberg Service Road up to the Horsetooth Rock Trail, and turn left, continuing on the foot trail up to the Wathan/Westridge Trail junction. Turn right off of the Horsetooth Rock Trail onto the Wathan Trail and continue straight (stay left) onto the Westridge Trail and follow it north to Towers Road. Take a right on Towers and the aid station will be right around the corner.
From the Towers aid station, take a left on the Mill Creek Trail and follow it all the way back to the Arthurs Trailhead in Lory State Park. Midway down Mill Creek Trail, watch for a sharp left turn at the Loggers junction. Shortly after you enter Lory State Park, the Mill Creek Trail will come to a T junction. Take the right onto the Mill Creek Link Trail and follow that to the South Valley Trail and the Arthurs Rock trailhead.
Start up the Arthurs Rock Trail and about 3/4 of a mile up, take a sharp left to connect to the Howard Trail. Follow Howard all the way up and around the back side of Arthurs Rock. Take a sharp left onto the Timber Trail behind the rock. The first part of Timber is a 4WD logging road. About 3/4 mile down the road, take the 90 degree right turn onto the Timber singletrack trail. Keep left past Well Gulch and follow Timber all the way to the Timber Trail on the valley floor. Exit the Timber trailhead and take the short connector trail back to the Soldier Canyon start/finish.
50 Milers will run the same 25 mile loop in reverse and from the last stop at the Arthurs trailhead runners will stay on the East Valley Trail all the way to the finish area.
