San Francisco to San Jose the long and scenic way. The first half of the ride features spectacular ocean views, cliffs, beaches, rolling hills, and some dirt roads for good measure. The second half is a true mountain stage, with long climbs through stunning forests of oak, bay, fir, and redwood. The course traverses the largest stand of ancient Coast Redwoods south of San Francisco. The name is a play on Bonny Doon, a lungbusting 2500ft vertical climb at mile 75 that was also featured in the Tour of California.
