From the issue Protecting Our Turf
According to the International Mountain Biking Association (IMBA),
there are more than three million mountain bikers in our state. That's a lot of knobby tires, and balancing demand and supply is not always easy. IMBA works with local clubs like the Bicycle Trails Council of Marin (BTCM) and the Bicycle Trails Council of the East Bay (BTCEB) to keep responsible mountain biking trails open to the public. In Marin, the Tamarancho Trail—a velvety singletrack loop in the redwood forest by Mt. Tam—is a classic example of the BTCM working with private land owners to develop and sustain stellar riding. Along the Lost Coast, IMBA and Humboldt County's Big Foot Mountain Bike Club are constructing an epic, 45-mile point-to-point trail featuring two overnight campgrounds. And in Sonoma's Annadel State Park, IMBA has worked closely with park officials to shut down illegal trail building so that the park can remain open to bikers. IMBA operates globally to educate people about preservation and improve mountain biking experiences. Join the ride, click here.
