Marathon de San Francisco

Founded in 1977, the Marathon de San Francisco is held every year in late July in San Francisco, California, with temperatures typically between 54 and 66°F (12–19°C). The 2027 edition runs on July 24 and 25 and features an ultramarathon (52.4 miles / 84.3 km, also offered as a relay for two), the marathon (26.2 miles / 42.2 km, about 1,310 ft / 400 m of elevation gain), two half marathons (13.1 miles / 21.1 km), The Bridge Half and The City Half, a 10K and a 5K on each day.

The race starts on the Embarcadero, the city's waterfront near the Bay Bridge. The course passes through several landmark neighborhoods: Fisherman's Wharf, known for its seafood restaurants; Marina Green, with views of the Golden Gate Bridge; and Crissy Field, a former military airfield turned recreation area with a marsh and beach. Runners then cross the Golden Gate Bridge before passing the Chase Center, home of the Golden State Warriors.

The first edition in 1977 drew 900 runners; today the event brings together several thousand each year. The course record is held by Simeon Kigen in 2:10:18.
