Horsetooth Mountain Open Space

The Quad Rock 50 and 25 mile trail races will start and finish at Lory State Park and the majority of the route will be run on Lory Park trails. The race will start at 5:30am and will end at 7:30pm. DNR trails will be in use from 6:30a - 6:00p


Detailed maps are available on the race website and can be provided via email or attachment if needed.

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.
• We will keep the clearing at the top of the hill open for emergency access.
• The team will meet at the Soderberg trailhead at 5:30am to drive up the road to set up on race morning.
• 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. (Primarily filled water coolers and equipment like tables and chairs that can sit safely overnight and save us a lot of time and extra trips up and down the hill on race day.)
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. Additional volunteer vehicles can be parked off site at race director Nick Clark’s house half a mile up Overhill Dr.
• 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. We will also enforce cut offs in Lory at the 25 mile turn around and at Arthur’s Rock trailhead so it is unlikely that we will have any runners lagging behind our cut off times in Horsetooth park.
• Volunteers will be available to provide recommendations for park users to access the course to see the event or find the best routes to avoid the runners.
• 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

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 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.
• An EMT team will be on standby for transport from the Soldier Canyon Finish area or Arthur’s Rock trailhead.
• Medical volunteers will be stationed at each aid station. (Horsetooth and Towers in Horsetooth Park and Arthur’s and Soldier Canyon in Lory Park)
• 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 in January.
