Old Man Winter Rally

Bundle up and get ready to RUN and/or RIDE Colorado’s best mixed terrain. Riders – choose 50km or 100km of dirt, snow, sweat, and beer rolling through the world-famous cycling mecca of Boulder County. Runners can crush the 10K run course, a fast, flat “Best of Lyons” tour, that integrates singletrack trails, red rock canyon, and gravel paths. Everybody gets luxury aid stations with real food and hydration, a hot meal and a cold beer at the finish line, and a killer post-ride party with great music, a fire pit, and a massive raffle.
