Tour of the Unknown Coast Century

This ride starts out easy enough, with a relatively flat run south from Ferndale to Humboldt Redwoods State Park. After about 30 miles, 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 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 make this one of California’s toughest 100 mile courses.

With its rough roads and steep twisty descents, this is not the ride for your super light low spoke count carbon wheels. Instead, consider installing a pair of 28c tires with tough sidewalls on a sturdy set of rims, check your brake pads (or bring disc brakes), and make sure your gearing is adequate for the steep climbs!

Rest stops will be at Mile 31, Mile 61 and Mile 83. Due to the distance and difficulty of terrain between rest stops, riders are advised carry two water bottles and resupply with pocket food at each rest stop. Additional food and water are available at the Honeydew store (Mile 53.5) and at the Petrolia store (Mile 68).

Ride fee with on line registration is $85 until Sept 1st, when it increases to $100 until on line registration closes on Sept 14th. THERE WILL BE NO ON SITE REGISTRATION FOR THIS YEAR’S EVENT.

This ride starts at 7am.
