The Alley Loop is not your typical Nordic Marathon… It stands both as a premier event, in addition to being Crested Butte’s most outrageous costume party of the year! The course winds its way through snow-laden streets, alleyways and narrow bridges through the heart of downtown Crested Butte. You’ll find yourself cheered by town revelers as you navigate a crazy gliding costume assemblage… Racers are sometimes forced into making daring passes and depending on their luck, may even get waylaid on a bridge for a moment. Once you make it through town, you are rewarded by pristine tracks and exhilarating vistas throughout the Crested Butte Nordic trail network. Check out full details here
