Runners follow an out-and-back course at the Stinson Beach Half Marathon, which starts and finishes in Stinson Beach Park. From there, runners head in the direction of Mt. Tamalpais along the Dipsea and Steep Ravine trails, which is followed by a counter-clockwise loop along the Ben Johnson, Camp Eastwood and the Troop 80 trails, through Muir Woods and back to Cardiac Hill. The final stretch brings runners along the Dipsea Trail, back to the finish line at Stinson Beach.
