The UCC is the Ultimate Cross County Gravel Ride. Embark on an epic exploration of West and Southern Marin by bike. The journey begins with a flat, paved, easy spin to Sausalito from Mill Valley. Make your way all around the Marin Headlands on a number of gravel roads. Descend Dias Ridge into Muir Beach and then start climbing up Tam along Coastal. Take in the incredible coastal views along some of the best Southern Marin gravel roads. Hop on the pavement at Pantoll and descend Ridgecrest. The picturesque backdrop from the ridge never gets old and is seen in numerous car commercials. From there, your journey north along the Bolinas Ridge begins. The ridge is one of the best kept secrets of Marin. Immerse yourself in everything from redwood groves to cow pastures as you make your way up the county. Mix it up with a loop with part of Highway 1 before retracing your steps along Bolinas Ridge. Next, you will climb both pavement and dirt to the East Peak of Mt Tam. After multiple hours in the saddle and finishing the climbing for the day, reward yourself with the unbeatable 360-degree views of the ocean to the West, Marin's natural beauty to the North, and all across the Bay Area to the south and east. From the top, enjoy a final dirt descent back to Studio Velo.
