Tour of the Unknown Coast Century

This ride starts out easy enough, across the flat Eel River Valley. A few small hills on the way to Rio Dell and Scotia will wake up the legs before riders reach the Avenue of the Giants. At Mile 30, the route turns west under Highway 101 onto Bull Creek Flats Road, and for the next few miles riders will enjoy some of the smoothest pavement in Humboldt County . . . but not for long! Things get serious at Mile 39 when riders begin the seven mile climb up to Panther Gap, the high point of the ride at 2700 feet of elevation. And the adventure truly starts on the downhill to Honeydew followed by the trip north through the wild and scenic Mattole Valley. Rough pavement (including several stretches of gravel road), the inevitable headwind along the coast and the formidable Wall and Endless Hills which stand between tired legs and the finish line in Ferndale make this one of California’s toughest 100 mile courses.

The first rest stop is in Rio Dell at Mile 14; the second rest stop is at the Immortal Tree, Mile 26; the third rest stop is at Mile 39, at the base of the Panther Gap climb. Lunch will be provided at the Mattole Grange at Mile 62, and a final rest stop is located at the base of the Wall, Mile 79. After this last rest stop, riders will still have 20 miles and 3,000 feet of climbing to go before reaching the finish line, and are advised to resupply accordingly.

Riders who are concerned about long climbs, steep descents and rough pavement will prefer our new Avenue of the Giants century route.

Ride fee is $90. This ride starts at 7am.

NOTE: Tour of the Unknown Coast Century riders are encouraged to set off before the 7 am mass start if necessary in order to finish in time to enjoy the post ride festivities. The post ride meal will be served until 6 pm. Riders not on pace to finish by 7 pm will be sagged forward.
