Best of the Bay Double Century routes

The BEST OF THE BAY Double Century can be broken down into the following three segments:

  • A 55-mile rural and scenic trip from Castro Valley through the East Bay hills, up to Grizzly Peak and down the other side, and returning through those hills to our headquarters in Castro Valley.
  • A 53-mile ride from Castro Valley to Mt. Diablo, climbing up the South Gate road, descending the same road, and followed by a gentle ride up Bollinger Canyon to our lunch stop at Las Trampas Regional Wilderness.
  • A 90-mile ramble south on Bollinger Canyon Road, San Ramon Valley Blvd., and Foothill Rd. to the Sunol-Ohlone Regional Park rest stop. The route then heads through Pleasanton, and continues east through the Livermore vineyards, and north on Collier Canyon towards Mt. Diablo. This time you won’t climb Mt. Diablo, but cycle past it to Danville, before heading south to Dublin, and finally descend to the finish in Castro Valley.
