Colorado Youth Outdoors

Our host, Colorado Youth Outdoors, is a 501(c)3 nonprofit organization. They are all about building relationships through outdoor recreation. We strongly encourage all of our entrants to raise support for CYO as part of their race. Ask friends and family to challenge you with a per-lap donation, or simply make a one-time gift. Runners can also donate as part of their registration.

Recognition and awards will be given for the three top fundraisers overall, as well as those achieving $200, $500 and $1000 tiers.

Gnar Runners will be donating $0.05 for every lap completed by every runner – so get your booty moving!

Colorado Youth Outdoors is where Relationships grow. They teach archery, survival skills, spin & fly fishing, fly tying and shooting sports to teens and their adults. While you and your teen are outside having fun together, they have discussions around participation, appreciation, communication, and dedication. These aren’t just words; they’re action items for building relationships. The goal: Time Well Spent building healthy lifelong relationships. CYO is a 501(c)(3) nonprofit.

Swift Ponds (CYO’s campus) is a beautiful 220 acre property on the east side of I-25 and about a mile south of Harmony road in Fort Collins Colorado. The Swift Ponds property was purchased by Louis Swift in 1969. Louis Swift was a visionary who had a dream of turning his newly purchased property into a great fishery, sanctuary for wildlife and an educational and recreational property for the community.

Transfer Credit & Distance Change Policy

If you are not able to race, we will be able to offer a race transfer credit that can be applied to any future Gnar Runners race (valid for 12 months). Credit deadlines are as follows:

You will receive an email when registration opens for the following year with a link to claim your credit.

Registered runners may also switch between race durations. Runners can pay the additional registration fee to upgrade their duration. There is no charge to downgrade your duration.

Runners who switch durations on Thursday or before will be eligible for awards in their new race duration category. Race day switches are not eligible for awards.

Cancellation Policy

With the exception of waitlist transfers, entries are non-refundable and non-transferable. In the event the race is cancelled due to extreme weather, fire, disease or for some other unforeseeable event, we cannot offer refunds or credits.

Course & Aid Stations

The amount of vertical/gain loss on the loop is ZERO (or at least it’s so small that any mapping software can’t get beyond the margin of error!)

Runners will reverse direction on the loop every 6 hours. Reversal notices will be posted at the start/finish. When you hear a reversal announced, COMPLETE THE LOOP YOU’RE ON before changing direction.

There will be mass starts available every 6 hours. 24hr runners will (of course) start at 8:00a. 12hr/6hr runners may start at their choice of 8:00a, 2:00p, or 8:00p. (Or even 2:00a for any truly crazy 6hr folks).

The course has been submitted for certification via USATF. The official measured loop distance is 1.00022mi – close enough for ya??

For those looking to achieve a marathon finish, we will have a course marking placed at the exact spot where that distance is achieved.

Aid Stations

The Start/Finish pavilion will have a full-service aid station, available every 1 mile lap. Vegetarian, vegan, and gluten free options will be available constantly. Options will include:

  • Gnarly Nutrition sports drink.
  • Water and ice
  • Salty snacks: Pretzels, potato chips, corn chips
  • Fruit: Oranges and Bananas plus additional variety depending on seasonal availability
  • Sweets: Cookies, M&M’s, Gummy bears
  • Soda: Coke, Ginger Ale
  • Hot Soup/Broth
  • Hot Drinks – Coffee, Tea, Cocoa
  • Hot Sandwiches/Quesadillas – Grilled Cheese, Grilled Ham & Cheese
  • Bacon

***There will be GF/Vegan alternatives for nearly all non-GF/V standard offerings. These are typically held back to save them for those who need them, so please ASK! Also note that while we will do our best to keep utensils and trays separated for these as well as common allergens, this is the backcountry and cross-contamination can occur.

While we will provide plenty of electrolyte options in drink mix and salty real foods, we deem the risks associated with salt in concentrated pill form to be more than we’re comfortable providing. We won’t restrict runners from using their own salt caps, but will not have them available at aid stations.

Crew/Runner Gear

Runners will be allowed to set up their own personal aid station along the loop. Details TBD.

Family and friends will be allowed assist their runners along most (if not all) of the course. Details TBD.

Runners may take breaks as they choose during their race.

We plan to have a warm indoor space at the Lodge available for the duration for runners/crews to use as needed. It is approximately 0.25mi from the nearest point of the loop course on the opposite end of the campus from the pavilion.


There are two permanent restrooms at the start/finish pavilion. We will also stage additional porto(s) at the halfway point of the loop.

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 the Race Directors on race day or contact us ahead of race day here.

  1. Runners must cross the lap timing mat ONLY upon the completion of a full loop.
  2. If a runner leaves the course (including to spend time in aid), THEY MUST RETURN TO THE COURSE AT THE EXACT SAME SPOT to continue.
  3. If a runner leaves the course and a directional change takes place while they are off course, they must finish their partial loop in the same direction they were originally traveling before reversing.
  4. Runners may start and stop their efforts at any time, taking as many or as long of breaks as they wish (even leave the campus) as long as they abide by the first three rules. Runners do not have to inform staff about breaks.
  5. Only full laps will be counted in the runners’ total. For purposes of tiebreakers, the first one to finish the last lap will be declared the winner.
    • If a runner is pursuing a national/international record or qualifying standard, we will be equipped with an on-site Jones Counter to measure partial final laps. Those individuals should declare their intentions to the Race Director prior to their start.
  6. RELAY TEAMS: Multiple team members may be on the track at a time, but the team will have one bib and only laps for the bib holder will count toward the team’s total.
  7. Purposeful littering is prohibited and will result in an immediate disqualification.
  8. No short cutting.
  9. No mechanical aid (poles, traction devices, etc.) unless approved by race staff prior to the race for a specific reason.
