Whether you’re flying solo or teaming up with friends, this classic test of stamina is not to be missed!
The Challenge: Race against the clock as an individual or in teams of 2 or 4 to see how many laps you can conquer on our 1.3 mile 1,800-vertical-foot Sun King uphill route in 12 hours. Skin up, ski down, and repeat—how far can you push yourself?
Key Details:
Bib & Schwag Pick-up: Grab your race bibs and gear at Sunlight Ski & Bike (downtown) on Friday, Jan 23rd, from 5-7 PM, or at the Sunlight lodge on race day from 5-5:30 AM. We encourage as many racers as possible to join us downtown on Friday!
Required Gear: All racers must have a headlamp, helmet, and DH-rated skis or a split-board. Helmets are mandatory for all downhill segments—safety first! Note: Snowshoes and uphill-only skis are not allowed.
