A beautiful century ride up along the Calaveras Reservoir to Sunol, then continue north through Pleasanton and on to Livermore with moderate climbs of Del Valle and Corral Hollow.

We take a break in the Del Valle park (mile 43), with restrooms and water. Return back with the out-and-back on Corral Holow then return through Pleasanton and via the reverse route along Calaveras Reservoir to the start. Light food and drinks at Sunol Corner market (miles 21 and 82) but otherwise bring your nourishment. We will regroup at summits but keep the breaks somewhat short since we need to cover a lot of ground.

Start/end at Berryessa Community Center which has restrooms and water. Start location: Berryessa Community Center [Route Link]
