2021 Event Date will be announced soon.


Welcome to the Tour of the Unknown Coast & Avenue of the Giants cycling event! For over forty years, we’ve been welcoming cyclists of all ages and abilities to join us for a day of fun and fellowship on two wheels in Humboldt County, CA. You can choose your own adventure from our selection of routes, including the classic Tour of the Unknown Coast century ride, our new Avenue of the Giants century ride, a 100K ride, a 50 mile ride, a 22 mile ride and a 10 mile family ride.

All riders will receive a Finishers Patch, and we’ll have t-shirts for sale at the event. After your ride, stick around for the post-ride festivities, including a deep pit barbecue lunch and live music.
