The Quadruple Bypass (AKA: The Century from Hell)

Climb, climb, climb and then climb some more. This is definitely one of the toughest mixed terrain day rides in the world. Starting and ending in Georgetown, the entire ride is a high altitude loop connecting dirt and paved roads, single track, old pack trails and jeep trails. Just under 100 miles long and a bit over 10,000 vertical feet of climbing, this ride crosses 4 big named passes and one unnamed pass. Kenosha and Loveland Passes are paved, Guanella and Georgia Passes are dirt. The ride also travels a considerable distance along the Continental Divide at over 12,500 ft high and follows the Colorado Trail for one leg.

This route is still preliminary.
