Karen Hornbostel Memorial Time Trial Series
2026-05-13, 2026-05-20, 2026-05-27 | Cherry Creek State Park, CO
Since 1991, the KHMTT has been a spring rite of passage—Wednesday evenings at Cherry Creek State Park—where riders gather to test themselves against Colorado’s mercurial weather and a deceptively beautiful course.
We race with purpose. The KHMTT is a fundraiser supporting the Cancer Fitness Institute—founded in memory of Karen Hornbostel—and Bicycle Colorado. Karen Hornbostel was a four‑time masters national road champion who, despite a 13‑year battle with metastatic breast cancer, pioneered a groundbreaking fitness program for cancer patients. Her vision grew into what is today the Cancer Fitness Institute, improving the quality of life for thousands of survivors. Her courage and leadership continue to inspire every ride.
The COBRAS and the KHMTT are proud to support these organizations. When you ride with us, you’re not just chasing personal bests—you’re helping fund life‑changing programs and safer streets for cyclists across the state.

Outlaw Gravel
2026-05-31 | Steamboat Springs, CO, Steamboat Springs, CO
Outlaw Gravel is a new gravel cycling event based in Steamboat Springs on May 31. Designed for both experienced racers and riders new to competition, the event introduces a timed-segment format that rewards strategy as much as strength.
Riders will take on multiple professionally timed gravel segments across the South Valley, connected by neutral sections where they can recover, refuel, and ride at their own pace. The course features rolling gravel, punchy climbs, open ranchland, and wide mountain views that define the Steamboat riding experience.
Participants can race solo or as part of a team of 2 or 4, making it as competitive or social as they want it to be.
The day starts and finishes at Olympian Hall, where riders and spectators come together for a post-race celebration featuring live music, food, and cold drinks. The event is designed to be as welcoming for friends, family, and the local community as it is for racers.
Outlaw Gravel is proud to support the Dirt to Snow – Mark Satkiewicz Legacy Fund, with a portion of proceeds going toward local youth programs and community initiatives.
Riders choose between two routes:
Long Course — 66 miles
Short Course — 40 miles
Both follow the same enduro format where timed segments decide the race.
Your combined time across all timed segments determines the winners — solo riders and teams with the fastest cumulative segment times earn the podium.
Push when it counts.
Recover when it doesn’t.
