Editor’s note: Copper Mountain Resort has canceled the event.

Copper Mountain Resort will host the Downhill to Duke’s six-hour mountain bike challenge Saturday, Sept. 18, as the final mountain bike race of the summer.

The event will be a team competition consisting of two to four riders per team. Points are awarded for completing different sections of the resort’s expanding trail network throughout the six-hour competition window.

Rider check-in will be from 8-8:30 a.m. at Eagle’s Landing with the race set to start at 9 a.m. Mountain bikers will have through 3 p.m. to ride as many trail sections as possible.

All riders will ride the Upper Elk Alley/Red Tail section from Solitude to the split as well as the bottom section of Red Tail, which will have no point value. Trail sections earning one point each include: Upper Red Tail, 2 Bucks, Upper Elk Alley, Upper Fawn-Tastic, Elk Alley, Lower Elk Alley and Red Tail.

After riding each trail, teams can ride whichever trails they want to earn more points, as course marshals will be on course recording riders and teams as they pass. Whichever team records the most points wins.

Happy hour and an awards party will follow the event at Downhill Duke’s in the Center Village base area at about 3:30 p.m. Awards will be given for first through third places.
