Horsetooth Mountain Open Space

The 9th annual running of the Quad Rock 25 & 50 mile trail races will start and finish in Lory State Park, using mainly Lory SP trails, with a 10-mile section of the course utilizing trails (Sawmill, Towers, Mill Creek, Spring Creek, Stout, Falls, Horsetooth Rock & Westridge) in Horsetooth Mountain Park. Two runner aid stations would be located within the park at the intersections of the Mill Creek and Spring Creek Trails on Towers Road and at the Upper Horsetooth Mountain Park trailhead.


25 and 50 Mile runners will enter Horsetooth Mountain Park from Lory on the South Valley Trail and will run up Sawmill to Stout, Stout to Towers, up Towers to the aid station at the Spring Creek junction. From the aid station, they will run down Spring Creek and Horsetooth Falls to the Horsetooth Trailhead. From the aid station pavilion, runners will exit the trailhead via the west service drive and will run up Southridge to the Horsetooth Rock trail and across the Westridge trail back to Towers. Runners will exit Horsetooth Park via Mill Creek.

50 Mile runners will return for a second loop in the reverse direction entering Horsetooth Park via Mill Creek and returning to Lory Park via Sawmill and the South Valley trail.

The course will be marked on Friday before the race with pink flagging tape. Flour will be used for directional arrows at major turns. All course flagging will be removed immediately after the last runner comes through on race day.

Aid Station Teams and Schedule
Towers Aid Station: 5:30am to 5:30pm
• 2-3 vehicles parked at the top of Towers Rd at the Mill Creek/Spring Creek junction.
• Additional volunteer cars may be parked at the bottom of Towers Road inside the gate to avoid taking up any extra space in the Soderberg trailhead lot.
• The team will pack up and drive out by approximately 5:30pm after the last runners have passed through.
• If possible, we would like to access Towers to drive some supplies up on Friday before the race.

Horsetooth Aid Station: 6:00am to 9:00am / 11:00am to 4:45pm
• The Horsetooth Trailhead aid station team will arrive at 6:00am to set up in the second large pavilion to the west of the rest rooms.
• For the duration of the race, we would like to reserve 2 parking spaces for volunteers to have at least one car to shuttle volunteers and run for additional supplies and always have one vehicle on hand in case of an emergency.
• We will enforce a hard 4:35pm course cut off. Any runner who does not leave the Horsetooth aid station by 4:35pm will be pulled from the race and given a ride back to Lory with the volunteers.
• The aid station will pack up and leave by approximately 4:45pm.
Course sweeps will follow the last runners to pull flagging and pick up any trash on the trails. When we leave at the end of the day, there will be no trace of our event left in the park.
Runner Limits and Timeline
Loop 1: Maximum 400 Runners
Arrive at Horsetooth Trailhead: 6:50am
Last runners through Horsetooth Trailhead: 8:20am to 8:50am
Loop 2: Approximately 150 Runners
Arrive at Horsetooth Trailhead: 11:00am
Cut Off: 4:35pm
Signs will be posted 1-2 weeks in advance at all park access points (Lory trailheads, Blue Sky, Soderberg, and park border crossings) to notify users of the event.
During the race, runner’s crew and/or spectators may visit the Horsetooth Trailhead. We will inform family, crew, and spectators that there is a $9 day use fee to park at the trailhead and parking space is not guaranteed. We will give the runners an opportunity to send drop bags to the aid station with personal items that they might need for the race so additional crew support will not be required. Extra visitors at the trailhead will only be there to spectate and provide moral support.
Safety and Communications
• Ham radio volunteers will be available at each aid station at the Soldier Canyon Start/Finish, Arthur’s Rock Trailhead, Towers, and the Horsetooth Trailhead.
• Aid station captains will keep track of all runners checked through their stations and updates will be relayed to the finish via the ham radio operators. We will also send out course sweeps behind the last runners as a final safety precaution.
• Aid station captains and race directors will also have working cell phones that are useable throughout the park. A list of contacts and numbers will be shared with the Larimer rangers on duty during race day.
• A Poudre Valley Ambulance EMT team will be on standby for transport from the Soldier Canyon Finish area or Arthur’s Rock trailhead.
• In case of an emergency, aid station captains will be instructed to contact the ranger on duty immediately to let them facilitate any necessary emergency response. Ham radio volunteers will be available to relay emergency messages to the Start/Finish. If a ranger is not immediately available, our volunteers can simply call 911 to have dispatch connect directly to the right person on duty.
• Insurance certificates will be provided after our annual policy is renewed around December or January.
