Get geared-up for Crested Butte's biggest costume party and Nordic event of the year. Sign up for 5K, 10K, half-marathon, and full-marathon races and sign the kids up for either the 1.5K or 3K kids races. All courses take you through the snow-covered allyways of downtown Crested Butte and some along the pristinely-groomed Nordic trails on the town's outskirts. Celebrate the end of the race at the awards after-party held at Montanya Rum Distillery. Sat 9 a.m.
