Our BOB ride has grown. We now offer a single-century and an official CTC double-century option. Both rides start and finish in Castro Valley, California, the home of Cherry City Cyclists. Our double-century route has three legs on which you will experience many of the best and most memorable cycling roads offered in the San Francisco Bay Area.

The first leg has many smaller climbs and descents as you head North to Grizzly Peak and back; it will warm you up without using you up. On the second leg, you climb and descend Mt. Diablo - so you do the hardest part of our route while you are at your best. Then the third leg takes you through three other great cycling experiences offered in the Bay Area: Calaveras Rd., the Livermore vineyards, and the Mt. Diablo foothills. The last 60 miles are gentle so you can finish the double-century without any significant, challenging climbs.

Our single-century option includes Leg 2 and the Calaveras Road portion of the double-century route.
