Riders can choose 50KM or 100KM of gravel, snow, climbs, and thrills. Runners can crush the 5K or 10KM course that provides the best of Lyons, CO - single track trails, red rock canyon, and gravel paths. 

On course, we’ll have aid stations with great food and hydration and keep an eye out for our 100+ ‘snowflake’ prizes. All participants will receive a hot meal, a cold beer, and access to the ragin’ after party in Lyons with live music, s’mores, bonfires, and lots of fun vendors !
