Run The Rockies Trail Race

Run the Rockies Trail 5k, 10k & Half Marathon

Run the Rockies is a trail race held on the Frisco Peninsula trails with views of Dillon Reservoir and the Ten Mile Range. All races start and finish at the Frisco Nordic Center and follow single track and dirt road trails. For 2026 the courses run counter clockwise on the Perimeter Trail and include a lakeshore finish.

Distances:

• 5k
• 10k
• Half marathon

The course will be well marked with pink flagging and directional arrows; course marshals will staff key junctions and aid stations. Maps and Strava routes will be updated by February 6, 2026. Pre-registration opens February 6, 2026 and closes at 12:00pm on August 6, 2026; pre-registration is encouraged as the event may sell out. If space remains, day-of registration is available at packet pick-up.

Registration includes a marked course, stocked aid stations, professional chip timing, post-race food, post-race beer for those 21 and older, and a commemorative gift; a hat is guaranteed for racers who register before July 1, 2026. Packet and bib pickup occur the day before and the morning of the race; participants must complete an online waiver to receive a bib.

Aid stations: 10k runners have two stations (miles 1.4 and 3.9); half marathon runners have three (miles 3.1, 8.3, and 10.9); 5k has no aid stations. Stations provide water, Skratch hydration mix, fruit, M&M’s, pretzels, gummy bears, and hand sanitizer. Racers are encouraged to carry personal hydration. Trails are on Town of Frisco and US Forest Service land; strollers and pets are not permitted. Music users should wear one ear bud only. Overall and age-category prizes are awarded; a post-race plaza party offers food, music, and beer for those 21 and older. Visit the organization's website for the most recent information.
