Northern Colorado and Southern Wyoming high school racers traveled to Nathrop on Saturday, October 10th, 2026, for Race #4 of the Colorado High School Cycling League season, the Chalk Creek Stampede. Competing at an elevation of roughly 7,700 feet in the Arkansas River Valley beneath Mount Princeton, the Platte Conference faced dry, fast conditions, rolling terrain and sharp, punchy climbs. Varsity fields completed three laps, while Junior Varsity, Sophomore and Freshman categories tackled two laps, with 372 individual finishers crossing the line during the final regular-season stop.
Regardless of where they finished on paper, every athlete who competed this season deserves credit for the work, commitment and determination it took to get to the start line and race. All Northern Colorado athletes featured in this recap train and cheer alongside one another under the SendTown Bike Club umbrella, representing their respective high schools while sharing a broader cycling community.

Trailcraft Cycles
YGR’s coverage of the 2026 High School Mountain Bike season is brought to you by Trailcraft Cycles, born and raised right here in Fort Collins, Colorado. Trailcraft now offers 29-inch full-suspension and hardtail mountain bikes in a full range of adult sizes. Check out the new carbon 120/120 Maxwell full-suspension and the Timber hardtail at trailcraftcycles.com.
How NoCo Athletes Participate
Local athletes race for their high school. However, if a student is homeschooled, attends a private school, or their high school does not have a mountain bike team, they race for the high school closest to their home address. This policy allows students from other cities to join Fort Collins high school teams if their local area doesn’t have a program.
All NoCo athletes train together and are supported by SendTown Bike Club’s Ciclismo Racing program. On race day, they race for their high school, wearing their high school kit, but all hang out and support each other under the SendTown tents.  SendTown provides comprehensive support, including organizing practices, paying coaches, and managing all race-day operations. The Ciclismo Racing program has a robust network of 60+ athletes and roughly a dozen coaches and staff who work to develop training plans and foster a supportive team environment.
Races and Categories
The league’s race format includes different categories for both boys and girls: varsity, junior varsity, sophomore, and freshman. This tiered system ensures fair and competitive racing for riders of all experience levels.
Throughout the season, Platte Region races are held at various locations, including Leadville, Steamboat, Frisco, Canyon City, Eagle, and Nathrop, culminating in the State Championships in Glenwood Springs. The league’s popularity is evident in its numbers, with around 1500 high school athletes participating in the opening-weekend races alone.
