Arapahoe Basin Ski Area held its uphill and downhill ski adventure race, the Spyder Grind, Saturday morning.
The race is designed to both introduce new participants to backcountry skiing and challenge the veteran skier.
Races are modeled after European randonee events, in which competitors begin on foot and run to clip into their skis.
They ascend the mountain under their own power, then ski down. The total vertical gain was about 4,000 feet in the race category and 2,000 feet for the recreational category. Helmets are recommended for all racers.
A post-race party and awards ceremony was held in the base area with a raffle, free beer and music for competitors.
