Karen Hornbostel Memorial Time Trial Series
2026-05-27, 2026-05-20 | 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.

2026 Dates:
April 8, 15, 22, 29
