San Francisco Half Marathon®

San Francisco Half Marathon is held in San Francisco, California, on February 7, 2027. Three distances share the morning: the half marathon (13.1 miles) and the 10K (6.2 miles) both start at 8:00 a.m., with the 5K (3.1 miles) setting off just ahead of them at 7:50 a.m. Elevation gain is not listed for any of the courses.

San Francisco is a hilly city, so treat the half marathon here as an effort-based race rather than a splits-based one, and put a weekly hill session into your build: repeats of two to four minutes uphill, jogging back down, do more for you than extra flat mileage. A 12- to 16-week block with a long run reaching 11 or 12 miles will get most runners to the line ready. The 10K is a sound choice if you want the same morning at a shorter distance, and the 5K, going off first, suits families and anyone easing back into racing.
