Our event includes an official CTC double century as well as a single century option. Both rides start and finish in Castro Valley, California.
Our double century route has three segments on which we include an experience filled with many of the best and most memorable cycling roads offered in the San Francisco Bay Area. The first segment has many small climbs and descents heading North to Grizzly Peak and back.
The most challenging part of the route is the second segment, which climbs and descends Mt. Diablo.
The third and final segment of the double century ride travels to these other great cycling offerings in the Bay Area: Sunol-Ohlone Regional Park, the Livermore vineyards, and the foothills of Mt. Diablo. The final 60 miles are less demanding, resulting in a finish without any significant challenging climbs.
