2027 Kaiser Permanente San Francisco Half Marathon & 5K

The Kaiser Permanente San Francisco Half Marathon & 5K has been a February tradition since 2002, now drawing nearly 4,100 runners to Golden Gate Park and the Great Highway. The course winds through the park's tree-lined paths before hitting the open coastal road, where the Pacific Ocean stretches to the horizon. With cool, fog-tinged air and a winning time around 67 minutes, this is a fast, flat route built for PRs—about 13% of runners return year after year.

The atmosphere is buoyed by a crowd of thousands and the sheer energy of running alongside the ocean. The finish line in the park offers post-race festivities, and the mild weather—typically in the mid-50s—makes for ideal racing conditions. Whether you're chasing a Boston qualifier or just taking in the views, this race delivers a classic San Francisco experience.
