DSP has been an amazing force for good in Denver.

From getting the sidewalk ordinance passed to advocating for protected bike lanes and Bus Rapid Transit, they are a force for good in Denver. Come out to support them in developing a sustainable funding source of grassroots donations!
We recognize times are hard, and everyone who supports DSP in different ways is welcome. No donation is required. For those who are able, a suggested ongoing donation of $10/month is encouraged to help set up a predictable funding source. Please RSVP for the event at the event link.

Karen Hornbostel Memorial Time Trial Series
2026-05-20, 2026-05-13 | 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.
