The Tour of the Unknown Coast was formed in 1978 with the following mission:

    • To organize an annual bicycling event in Northern California
    • To encourage bicycle riders of all levels of cycling ability to participate
    • To educate the general public regarding safe cycling practices and techniques
    • To generate funds which are donated to non-profit organizations in the Northern California area


Before it became an organized event, the route used today for the Tour of the Unknown Coast was a favorite loop among Humboldt County’s serious cyclists. This 100-mile lap has unparalleled beauty and challenges. In 1977, a group of these hardcore riders got together for an informal race for bragging rights over who could be first to complete what they had dubbed the “Tour of the Unknown Coast.” The following year it grew from that haphazard beginning to become an actual event.

Over time, event organizers recognized that not everyone wants to suffer through 100 miles in a day, and shorter routes were introduced including the 50 mile and 100K rides. Eventually, the TUC expanded even further to encourage riders of all ages and abilities to take part by adding the family friendly 22 mile and 10 mile routes.

The TUC is a 501(c)(3) organization, and supports other non-profit organizations in the North Coast community. The TUC has donated more than $170,000 to these groups in return for their support of the event. The 2019 donation recipients are:
