The first Saturday of every December, a group of 3,000 cold-hearted runners, rebels and fitness freaks gather on the beautiful frozen tundra of the University of Colorado campus to conquer whatever nature throws their way. Finishers receive Cold Medals, frosty brews (or soft drinks), tasty treats and a few surprises. If you listen closely that time of year, and you might even hear our battle cry, “Let it snow, let it snow, let it snow!”
