About Our Race

THE SAN FRANCISCO MARATHON • JULY 26TH, 2020

The 42nd running of The San Francisco Marathon will take place on Sunday, July 28th, 2019. This USA Track & Field-certified Boston Marathon and Olympic Team Trials qualifier race attracts top endurance athletes and a fantastic community of runners from around the country and the globe. The race prides itself on its unique nature; like the city itself the race is more individual, the course more challenging, the terrain more beautiful – an event Bart Yasso, Chief Running Officer of Runner’s World, referred to as “challenging and beautiful…one of the country’s best big city marathons.” The San Francisco Marathon proudly hosts over 27,500 runners and rewards their efforts with unparalleled breathtaking views and a unique course that they will never forget.
