Karen Hornbostel Memorial Time Trial
at Cherry Creek State Park

2022 Dates:

March 23, 30
April 6, 13, 20, 27, May 4
Weather Make-up: May 11


Since 1991, the KHMTT has taken place Wednesday evenings in Cherry Creek State Park in early spring, and for 2022, we are returning to Spring!

The seven-week series will be starting March 23th.

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.

Like to race for free?

The KHMTT holds a safety record second to none in large part because of our many volunteers and supporters assisting racers, monitoring motor vehicles and directing traffic. Be a vital part the time trial series by being a volunteer and you can work and race the same night!

Never raced before and would like to try it?

Racing in a time trial is fun and one of the safest ways to race a road bike. You can race one night in the KHMTT for only $20 and we will help you get started.

Show and Go!

“Show and Go” allows you to reserve a start time for the remainder of the series, then on nights you want to race, just show up at the start line and go! 

How it works:

  • You register for Show and Go
  • Select your start time
  • Pay the $20 ($24 for two races per night) start time reserve fee via credit card
  • The first night you race, come by the registration table and pick up your bib.
  • Go to the start line and race!
  • When you want to race again, just show up at the start line and race!

Course Change

The course is now 9.6 miles! The course will finish with a long straight uphill climb the last mile before finish followed by a tight right-hand turn, then a quick downhill to the line. This change will allow our timers to stay in a vehicle (not under a tent) and they will be facing away from the sun. To check out the changes, go to What You Need to Know, The Details, The Course.

New Route to the Parking Area

Because of the extension of the course onto Swim Beach Access Road, vehicles entering the park going to the Smoky Hill Parking area are requested to use the East Boat Access Road (the road where the start line is located) to Swim Beach Access Road, then turn left to the Smoky Hill parking area.  That will prevent vehicles from driving on the actual course as racers approach the finish line.  To see the new vehicle route, go to What You Need to Know,  The Details, The Course.

Discounted Colorado Annual Park Passes

The COBRAS will once again provide the opportunity to purchase a Colorado State Parks Annual Pass during the series registration process for all participants who register for the series before September 29th.

Passes can be purchased at the discounted cost of $67.00 (normally $80.00) each.

Passes will be mailed about 10 days before the start of the series along with your bib. Due to changes in the way Colorado Parks and Wildlife now handles bulk purchases, we can no longer include the Water Basin fee. You will need to pay the Water Basin fee when you pick up your park pass. ($3.00)

Colorado Parks and Wildlife changed their bulk purchase program last year and now issue vouchers, which may be exchanged for an annual pass. We strongly suggest once you receive your voucher that you take it to a state park or regional office and exchange it for your actual pass before your first night of racing.

Addition of a Corridor in the Tower Loop Turn

The Tower Loop turn has always been problematic, as parked vehicles cannot always see racers entering the loop when backing out of a parking space.  This year we have added a corridor, separating racers from other vehicles in the loop. Racers will merge left as they enter the turn and stay left of the cones in the turn. When exiting the corridor, racers will merge right as they exit the loop back onto the main road.
