Grand Traverse 
Competitors are required to enter this nighttime ski race with a partner and prove to officials they can fix a broken binding in case of emergency. If you're aiming to finish among the first competitors, try to finish the 40-mile course from Crested Butte to Aspen around daybreak. Whenever you cross the finish line, you can enjoy an awards ceremony and cocktail party at Aspen's Elks Lodge. Sun midnight.
