A spectacular 78-mile loop cresting three Colorado Mountain passes – Fremont Pass (elevation 11,318’), Tennessee Pass (elevation 10,424’) and Vail Pass (elevation 10,666’). The course passes three ski areas and is littered with historic mining outposts and camp Hale, the training ground for the famous 10th Mountain Division. The total elevation gain for the course is 5,981 ft. A great day on two wheels.
