Race Analytics from

With a start beneath the towering redwoods in Golden Gate Park and a prized finish at Cupid’s Arrow along the Embarcadero, The San Francisco Marathon’s 2nd Half Marathon course winds through city streets, offering a locals’ only tour of the city’s treasured vistas. Racing beside the Conservatory of Flowers, through the Haight-Ashbury and Mission neighborhoods, beside AT&T Park, under the Bay Bridge and more, each runner’s journey unfolds against an unforgettable sense of place. Join our Full Marathoners as you take on 13.1 miles, the 2nd Half of our Full Marathon course.

Our 2nd Half Marathon is popular with runners looking to set a PR. Due to its low elevation profile and a gradual finishing descent toward the Embarcadero, many runners return to this course year after year to test their limits and reach new heights.
