This hilly route will begin at the Orinda BART station in the east parking (not the same side as the station). We'll ride out to El Sobrante and circumnavigate the San Pablo Reservoir, traveling over the hills known as the Three Bears on Bear Creek Rd. This loop is about 22 miles. Depending upon the ambitions of the group, we could keep riding with a possible lunch stop in Lafayette. Arrive in time to roll at 10am. Rain cancels.
