Welcome to the Quad Rock 50 and 25 mile trail races, an event put on by trail runners for trail runners.

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 stretches of Colorado’s mighty Rocky Mountains. Look east from the course’s high ridges and you’ll see the Great Plains extending into Nebraska as far as the eye can see. Look west and you’ll take in summit views, dominated 30 miles away by a towering Longs Peak.

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 and the stories flowing.

With the exception of the Arthur's Aid at mile 48.0, all aid stations will be fully stocked and staffed with volunteers.

On hot days we may have an additional water drop on the access road behind Arthur's Rock at about mile 21 on the first loop and mile 29 on the second loop. Please plan on carrying enough water from Arthur's or from the Finish area to get up and over the 7.6 mile leg. We will communicate yes/no on this water drop on race week.

All full service aid stations will stock the following items:

  • VFuel bulk gel and sports drink. (Please bring your own gel flask for refills)
  • Water and ice (ice may be limited at the Towers aid station)
  • Salty snacks: Pretzels, potato chips, corn chips
  • Fruit: Oranges and Bananas plus additional variety depending on what might be available
  • Sweets: Cookies, M&M's, Gummy bears
  • Soda: Coke, Ginger Ale

*Aid stations will not provide water cups. All runners are required to carry their own water bottle or hydration pack.

VFuel gel will be provided in bulk containers so please bring your own flask to fill at aid stations.

Time Cut-Offs

Course cut-offs will be enforced at the following aid stations:

  • Soldier Canyon (Mile 25) at 12:15pm. 6:45 Total time. **50 Mile Only**
  • Arthur's Trailhead at 2:10pm. 8:40 Total time (50 Mile) / 7:10 Total time (25 Mile). This cut-off is enforced in both directions - no traffic continues from Arthur's in either direction in either distance from Arthur's after 2:10p.
  • Horsetooth Trailhead (Mile 39.6) at 4:35pm. 11:05 Total time **50 Mile Only**

This is a challenging course so some runners may find it difficult to meet these cut-off times. Any 50 mile runner who drops out or fails to meet the course cut-offs after completing the first 25 mile loop will be given a finish time in the 25 mile race, but will not be eligible for 25 mile overall or age group awards.

Drop Bags

If you have any specific personal needs, drop bags will be allowed at the Horsetooth Trailhead (Mile 10.4 and 39.6) and Soldier Canyon (Mile 25.0 for the 50 milers).

Horsetooth Drop Bags must be dropped off at the start by 5am on race morning. We will not have a second transport shuttle for the later 25M start.

Soldier Canyon (Finish/25 mile turn) drop bags may be dropped off any time before the start of each race.

Please keep your drop bag to a reasonable size (small duffel bag or stuff sack). They should be clearly labeled with your name and bib number. Please do not leave any valuable items in your drop bags - volunteers are not responsible for lost items.

Drop bags will not be returned to the start until the Horsetooth Aid Station shuts down and packs up at the end of the day (after 5p). If you finish early and need your drop bag before heading home, you are welcome to drive around to the Horsetooth trailhead (about 30 minutes) to pick up your drop bag. Unclaimed bags will be left in a lost and found box at Altitude Running for two weeks before being donated.

Course Marking

The course will be well marked with pink flagging and pink pin flags. Important intersections will be supplemented with flour ground markings and directional arrows. On longer stretches of trail without intersections, confidence flagging will be placed approximately every quarter mile. Turns will be marked heavily.

Toilets

Permanent park restrooms are available at the Soldier Canyon, Arthur's, and Horsetooth trailheads. Additional portable toilets will be available for race participants at the Soldier Canyon start/finish.

Crew Access

Family and friends can meet their runners at the start/finish at Soldier Canyon, Arthur’s Trailhead, and the Horsetooth Trailhead. Runners will receive one pass into Lory State Park for the race. Any additional crew or family vehicles will need to pay the regular $9 park entrance fee. The Horsetooth Trailhead is separate from Lory State Park, and requires its own $9 day fee for Larimer County Parks. Carpooling is highly recommended to save on park fees and limit traffic and parking congestion at the trailheads – especially the Horsetooth trailhead, which is likely to be packed with regular park visitors.

All trails are open to the public, so family and friends are allowed to run, hike, or bike on the course; however, pacing or crewing outside designated aid stations is not allowed and will result in the disqualification of your runner.

The Arthur’s Rock Trailhead is easily accessed from the start/finish area by driving 2 miles south on the main Lory State Park access road.

The Horsetooth Mountain Park - Upper Trailhead is located approximately 13 miles - or 30 minutes - from Lory State Park. It can be accessed by taking Lodgepole Dr out of Lory State Park to County Road 23/Centennial, and then heading south (right) along the east side of Horsetooth Reservoir. After 4.5 miles on Centennial, make a right up the hill to stay on Co Rd 23 for another 1.5 miles. Make a right on County Road 38E and follow the road around the south side of the Reservoir for 4.5 miles. The Horsetooth Mountain Park trailhead is about a mile past the Canyon Bar and Grill at the crest of the hill, on the right.

Detailed Course Directions

Start to Arthur's Trailhead:

The race will start in the parking lot of the Soldier Canyon Picnic Area. Runners will follow the road out of the trailhead and head south on the Lodgepole Drive loop (where runner vehicles are parked) and will continue two miles down the main park road to the Arthur's trailhead.

Arthur's Trailhead to Towers Aid Station:

Take the first left into the Arthur's horse trailer parking lot to access the east side of the South Valley loop trail and run another mile. Immediately after crossing the Horsetooth Mountain Park border, turn right onto the Sawmill connector trail and continue up Sawmill to the Stout Trail. Take a left on Stout to connect over to Towers Rd, where the course takes a right up the hill to the Towers Aid Station at the intersection of Towers Rd and the Mill Creek / Spring Creek trails.

Towers Aid Station to Horsetooth Trailhead:

From the Towers aid station, turn left onto the Spring Creek Trail. Take the Spring Creek Trail all the way down to a three-way intersection after about 1.7 miles, turning left at the intersection to stay on the Spring Creek Trail. Stay straight to connect with the Horsetooth Falls Trail after half a mile and follow it another mile to the Horsetooth Mountain Park Trailhead and race aid station.

Horsetooth Trailhead to Towers Aid Station:

From the Horsetooth Trailhead, take the Soderberg service road up to the Horsetooth Rock Trail, and turn left, continuing on the hiking trail up to the Wathan/Westridge Trail junction. Turn right off the Horsetooth Rock Trail onto the Wathan/Westridge Trail and continue straight (stay left) on Westridge at the intersection of Wathan/Westridge shortly after you turn off the Horsetooth Rock Trail. Follow it north to Towers Rd. Take a right on Towers Rd and the aid station will be right around the corner.

Towers Aid Station to Arthur's Trailhead:

From the Towers Aid Station, take a left on the Mill Creek Trail and follow it all the way back to the Arthur's Trailhead in Lory State Park. Midway down Mill Creek, take a left at the Loggers T-junction. Shortly after you enter Lory State Park, the Mill Creek Trail will come to another T-junction. Take the right onto the Mill Creek Link Trail and follow that to the South Valley Trail, where you'll make a quick left to Arthur's Trailhead.

Arthur's Trailhead to Soldier Canyon Start/Finish Area:

Start up the Arthur's Rock Trail and about 3/4mi up, take a sharp left to connect to the Howard Trail. Take a right on Howard and follow it towards Arthur's Rock. At the T-junction with the Timber Trail under Arthurs Rock, take a left. The first part of the Timber Trail is a 4WD road. About 3/4mi down the road, take the 90 deg right turn onto the single track Timber Trail. Follow Timber all the way to the trailhead. Exit the Timber trailhead and take the short connector trail back to the Soldier Canyon start/finish.

50 Mile Finish:

50 Milers will run the same 25 mile loop in reverse, with one exception in the final 2 miles. From the last stop at Arthur's Trailhead, runners will stay on the East Valley Trail (not the park road) all the way to the finish at Soldier Canyon.


Race Rules

Race rules are designed to provide a safe and fair experience for everyone involved and to help ensure our ability to produce the race again next year. Major rule infractions by racers will result in immediate disqualification of the racer. Please do not argue with or harass our volunteers. Please direct any questions and feedback to us here.

  2. At each aid station (except the first time through Towers mile 7.3), volunteers will record runner bib numbers. Runners are responsible for making sure that aid station volunteers record their number. Please make sure that your bib number is visible from the front and call out and confirm your number when passing through an aid station. This is important so that we can keep track of runners and know that you are not lost or injured.
  3. If you need to drop out of the race for any reason, you must check out with the nearest aid station or course volunteer.
  4. Purposeful littering is prohibited and will result in an immediate disqualification.
