Try out bike racing at the Karen Hornbostel Memorial Time Trial Series

Have you ever dreamed about participating in a bicycle race, but been too intimidated or afraid of the dangers of riding in a big group, or just not sure where to start? The Karen Hornbostel Memorial Time Trial Series (KHMTT) held at Cherry Creek State Park each year is the perfect opportunity to dip your toe in the water!

Bicyclists newer to the sport might be wondering: what is a Time Trial? It is when one person at a time sets off from the starting line and races against the clock to the finish line. Finish times are then compared to those of other riders at the end. It’s great for first-time racers because you’re not jostling for space in a group, drafting (riding close behind each other) is not allowed, and you compete with other racers in your category or age group. Plus, you don’t have to have a fancy bike—just a common road bike and a helmet and you are good to go.

Cyclists of all talents and abilities take part in the KHMTT each year, including a lot of bicyclists who enjoy racing as well as recreational riding, maybe just like you.

By being part of the KHMTT, you are supporting bicycling in Colorado. Most of the profits from rider participation are invested back into the Colorado bicycling community, including in Bicycle Colorado!

The Karen Hornbostel Memorial Time Trial Series runs every Wednesday from September 8 through October 20 at Cherry Creek State Park. Interested? Head to the KHMTT first-timers website to learn all about time trials, what you need and the cost. Sign up to give it a try! And who knows? You may just get hooked!

We’re thrilled to see so many people out enjoying (and often rediscovering the joy of) riding a bike right now, and we’re asking ALL bicyclists to do their part to prevent the spread of #covid19 by wearing a mask or other face covering when out for a ride. Doing so keeps you, your loved ones, those around you, and all Coloradans safer while helping reduce stress on our medical system.

Thanks so much to everyone who has already purchased, and to @primalwear for supporting our efforts over the years. Ride on.

  • Tonight the #BicycleColorado team celebrated Stacey, our outgoing Development Director, with a virtual happy hour. Stacey has been an absolute rockstar for BC. We’re sad to see her leave, but thrilled for her as she heads out on a new adventure (hopefully in the #BikeAdvocacy space!) in North Carolina. Please join us in wishing her well!
