Join us for a weekend of fun and running on the beautiful trails near Fruita, Colorado. The weekend kicks off on Friday night with packet pickup and a dinner. Saturday is the trail marathon and 50K, followed that night with a racer party at a local brewery. Sunday’s events include a 10K, half marathon and kids’ races. Sunday’s races did sell out in 2018, so get in early.

We can’t wait to see you this April – hopefully with fresh legs and a powerful spirit, ready to start the racing season off right! We wish you all health, happiness, and smart training in the weeks to come!

These are challenging courses:

The Marathon will be a single loop connecting the desert trails of Kokopelli and adjacent trails. The course rolls between elevations of 4,500 and 5,400 feet with over 3.400 feet of climbing per loop. We will have five aid stations located throughout the course, at approximately five-mile intervals (the largest gap is 7 miles).

The 50K will be the Marathon course plus an additional 5mi loop, with six aid stations in total.

Aid Stations will be stocked with Hammer Gel, potato chips, peanut butter and jelly, chocolate, bananas, ice water and sports drink.

Additional food will be available at the turnaround/finish line (if racers need additional food on the course, they are advised to carry it with them). In addition, a certified Emergency Medical Technician will be in attendance.
