Old Man Winter Bike Rally & Run

Mask up, bundle up, and get ready to run and/or ride Colorado’s best mixed terrain!

We’re doing things different this year. We’re passionate about providing you with a memorable adventure and are adapting to county regulations to make it happen. You’ll have between February 6 - February 14 to complete your registered race on our iconic courses.

Riders can choose 50km or 100km of dirt, snow, climbs, and thrills. Runners can crush the 10km course that provides the best of Lyons, co - single track trails, red rock canyon, and gravel paths.

We’ll have aid stations with great food and hydration on course during the weekends. All participants will receive a ticket for a hot meal and a cold beer in Lyons. Everyone can compete and celebrate their adventure in a way they are comfortable.
