The Dipsea is well known for its scenic course and challenging trails. The race starts on Throckmorton Avenue in Mill Valley, near Miller Avenue, in front of the old train depot (now a bookstore). After traversing a few blocks in Mill Valley's downtown, runners climb 688 stairs (now 700 stairs, after the renovation of the middle section in Nov 2017) leading up the side of Mount Tamalpais, and then pass through Muir Woods National Monument, Mount Tamalpais State Park, and the Golden Gate National Recreation Area. The Dipsea Trail is the most direct route connecting the town of Mill Valley, located near the northwestern shores of Richardson Bay, with the village of Stinson Beach, situated along the Pacific coast. Stinson Beach is a popular tourist destination, located about a 30-minute drive north of San Francisco on Highway 1, via the Golden Gate Bridge. The ascent over the southern shoulder of Mount Tam reaches its apex around the top of Cardiac Hill, about 4.5 miles into the race.
