This is the toughest part of one of the most popular longer training rides in the San Francisco Bay area, and features a "Full Tam" from sea level to the summit of Mt Tamalpais at 2,571 feet (784 m). Check out the views along Highway 1 before you hit the climb. Be warned, there are a couple of false summits before you finally reach the end of the climb.
