Adventurous mixed terrain, mountain bike and all pavé rides and races in Northern California. Just north of Marin County, the birth of mountain biking lies the cradle of adventure riding and racing. The Hoppers are the original mixed-terrain adventure races/rides in North America. These "not gravel grinders" are some of the most eclectic, scenic, challenging and thrilling courses in the world. Join us in adventure, exploration and shred.

Come ride with us on February 22nd for a ride in a unique area nestled between Highway 505 and the Mendocino National Forest. Low Gap sold out quickly, so don’t wait to register for Huffmaster! ...

Join us for the classic Huffmaster starting in Maxwell, California. West of Hwy 5 and east of the Mendocino National Forest lies miles of rolling gravel roads and lightly traveled tarmac that few have seen on two wheels. Two routes to choose from-89 or 59 miles-and less climbing than a typical Hopper make these mixed-terrain routes a real treat.
