Since 1978, the Tour of the Unknown Coast has been touted as one of California’s toughest century rides, and among the most beautiful rides anywhere. Some would say that rough roads are part of the adventure on this ride, but we are still pleased to announce that road conditions on the course have improved in several locations, including the historically rough section on Bull Creek Flats Road as well as on the climb to Panther Gap and descent to Honeydew.

For 2019 we’re stepping up our game and adding the new Avenue of the Giants Century. This beautiful route through the redwoods features smooth pavement and significantly less climbing than the traditional century ride.

If 100 miles in a day isn’t your idea of fun, we’re still offering our 100K, 50 mile, 22 mile and 8 mile rides to suit every taste.
