Devil Mountain Double Century begins in San Ramon, California and has 20,000 ft. of climbing. The route climbs Mt. Diablo at sunrise, Altamont Pass, Mt. Hamilton, Morgan Territory, and Sierra Road. Of the seven doubles I've completed this one is my favorite. Pictures include; climbing Mt. Diablo, climbing Mt. Hamilton, night riding at mile 185, outside the finish "suite" at the San Ramon Marriot. Yum.
