The Old Man Winter Bike Rally was created to be THE winter adventure 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.
Choose the 50km option for a scenic spin along the paved and gravel farm roads on the east side of the Foothills Highway.
Choose the (roughly) 100k course to tackle some extra miles over beautiful rolling gravel roads North to the famed Carter Lake before returning back to Lyons.
The 5.4-mile run take you out and back in a Red Rock canyon that incorporates sections of the ever-popular Picture Rock Trail and “Lyons Fruit Loops”. It’s truly a “Best of Lyons’ course with big views, minimal elevation gain, and mixed terrain.
