Runners start the race at the spot known as Rodeo Beach and the Rodeo Lagoon across the bay from San Francisco’s Presidio, in Sausalito at the Golden Gate National Recreation Area. From there, participants follow a clockwise, out-and-back loop course through the area known as the Marin Headlands, which overlook the city and the Golden Gate Bridge.
