Do you dream of conquering all four of Aspen's mountains? Now's your chance to race through them all in one powder-filled day. Sign up with a partner to ski through the 12,000 feet of runs in the Sport Division (whichweaves skiiers along a path through the four mountains). If you're not up for that much elevation in one day, join the recreational division and keep your racing legs limited to Aspen Highlands and Aspen Mountain. First place prizes include Oakley watches and Giro helmets for the respective divisions. Head to the Limelight Hotel for the post-race awards ceremony, food, and beer. You'll deserve it. Sat 6 a.m.
