Oskar Blues Brewery presents the OLD MAN WINTER RALLY – an  epic day of winter adventure. 

Choose  50km or 100km of dirt, snow, sweat, and beer rolling through the world-famous cycling mecca of Boulder County, ColoRADo…from Lyons to Boulder and beyond. OR crush the 5.8-mile run course, a fast, flat “Best of Lyons” tour, that integrates single track trails, pavement and dirt roads for a frosty frolic through a spectacular winter landscape. 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, contests, and a massive raffle. It will be the most fun you have all winter!
