Karen Hornbostel Memorial Time Trial Series
Register for KHMTT
View the event website for more information.
Since 1991, the KHMTT has taken place on Wednesday evenings in Cherry Creek State Park in early spring.
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 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.
The KHMTT is now part of the Rocky Mountain Road Cup calendar.
