San Francisco Marathon 2027

The course is a counterclockwise loop that starts and finishes on the Embarcadero near the Ferry Building. It runs along the waterfront through Fisherman's Wharf and the Marina, crosses the Golden Gate Bridge into Marin County and back, then goes through the Presidio and Golden Gate Park, the Haight-Ashbury and Mission districts, and returns along the waterfront past Oracle Park. Terrain is hilly with roughly 1,700 ft of total elevation gain; notable climbs occur around miles 2-3 (Fort Mason), 11, 13, and 15-16, while the final 10K from about mile 21 is mostly downhill.
