About

Since 1991, the Chatfield has taken place on Wednesday evenings in Chatfield State Park in early spring.

The weather is a bit unpredictable (this is Colorado!), but that is what makes the Chatfield unique and challenging!

The course begins at the edge of the Cherry Creek Reservoir, winds through the wetlands southeast of the reservoir, and crosses back and forth the small creeks that supply the water for the reservoir.

The Chatfield series is a fundraiser for the Cancer Fitness Institute in memory of Karen Hornbostel, and Bicycle Colorado.

Karen Hornbostel was a four-time masters national road champion who battled metastatic breast cancer for over 13 years, yet courageously pioneered a fitness program for cancer patients that started what is today the Cancer Fitness Institute. Her work is still making a difference today in the quality of the lives of thousands of cancer survivors.

Bicycle Colorado envisions a Colorado where riding a bicycle is always safe and convenient for everyone, where bicycling is the top choice for recreation and everyday trips, and where the benefits of bicycling are experienced and valued by all people in our state.

The COBRAS and the Chatfield are proud to be able to contribute to these worthwhile organizations.
