The "Copper Triangle" (also known as the "Leadville Loop") is a truly classic Colorado mountain route that can be ridden in either direction. It is a beautiful ride in mid-late September when the Aspens are at the peak of their fall color.
The ride begins at the Copper Mountain Resort (or anywhere else along the route). If riding clockwise, the route heads south on Highway 91 over Fremont Pass past the Climax Molybdenum mine and then descends on through the valley to the north end of Leadville.
Turn northwest on Highway 24 where you will pass the remains of the training camp for the famed 10th Mountain Division of WWII before climbing Tennessee Pass and Battle Mountain, and descending down to Minturn, the low point of the ride.
A bike path then starts just north of I-70 to head back east through Vail, over Vail Pass and back to Copper Mountain Resort. The ride covers 79 miles and 5,900' of climbing.
The Copper Triangle can be ridden as a fully supported ride the first Saturday in August each year as a benefit for the Davis Phinney Foundation & Parkinson's Disease. Click here for more information on this Colorado Cyclist sponsored ride.
