Old Man Winter Bike Rally
The Old Man Winter Rally was created to be THE multi-sport winter event. With two bike courses and a one-of-a-kind running course, there is plenty of winter adventure for all runners and cyclists.
It is the one and only winter cycling festival that brings Boulder’s best riding to cyclists of all levels. From quiet country roads to scenic mountain lakes, we’ve got the distance and the terrain you’re after.
- The 50km route tours some of the scenic, rolling terrain that has made Boulder County, CO one of the country’s most popular gravel riding destinations.
- The 100km ride starts with the same country riding as the 50km course before sending cyclists on a roller coaster route of climbs and descents through the snow-filled canyons west of Boulder.
