Karen Hornbostel Memorial Time Trial
at Cherry Creek State Park

March 18, 25, April 1, 8, 15, 22, 29
Weather Make-up Date: May 6


Since 1991, the KHMTT has taken place Wednesday evenings in Cherry Creek State Park in early spring. The seven-week series will be starting on March 18th with a makeup date in case of a cancellation due to unforeseen weather conditions.

The weather is a bit unpredictable (this is Colorado!), but that is what makes the KHMTT 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 KHMTT series is a fundraiser for Cancer Fitness Institute in memory of Karen Hornbostel, 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. The COBRAS and the KHMTT are proud to be able to contribute to this worthwhile program.

The 2020 Karen Hornbostel Memorial Time Trial Series is presented by the COBRAS.
