Golden Gate Half Marathon & 5K

From there, the out-and-back course takes runners on a mostly westward route through the city streets, along Bay Street, Marina Boulevard and Mason Street on the way toward Lincoln Boulevard and the approaching roadway to the bridge.
Once on the bridge, runners follow the course all the way over to the other side at the Marin Headlands, and reach the turnaround point at North Vista Point, where they start the second half of the race.
On the course along the way back, runners follow a slightly different course in the last third of the race, as miles 10, 11 and 12 take the field along the Golden Gate Promenade along the beach of the Golden Gate National Recreation Area.
The course follows through here, and then along Marina Boulevard, all the way to the finish line back at the Aquatic Park near the pier. Participants will need to keep at most a 16-minute-per-mile pace, and the course will remain open for 3.5 hours.
