Old Man Winter Rally

Colorado’s favorite Epic Winter Adventure for runners and riders. Old Man
Winter Rally offers two bike course options: the 50km route tours some of
the scenic, rolling terrain that has made Boulder County, CO one of the
country¹s 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. The event also offers a 10km running race and a
Run/Bike combo that is popular for multi-sport athletes. All participants
are supported with well-stocked aid stations and a huge after party with
plenty of hot food, fire pits, and cold beer.
