Fundraising

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 (https://www.coloradoyo.org/) 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.

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.

The course is U.S.A.T.F. certified at 1.0002mi (ID# CO240003MWC (https://certifiedroadraces.com/certificate/?type=m&id=3636) ). The race is U.S.A.T.F. sanctioned, ID# 155337 (https://usatf.sport80.com/public/widget/6)

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:

* Sports drink * Gels * 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 * Burgers - Beef & Veggie with fixings

***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.

Richardson Hall (Lodge)

The CYO campus lodge (Richardson Hall) will be open for those who need a respite in a heated, indoor space during the event. Located approximately 0.2mi off the course loop at the southwest corner of the campus (opposite end of the start/finish/aid), it will have space available for crews & runners. Parking in its lot and crewing in and around the building is allowed. You're even welcome to nap inside, though we make no promises about quiet.
