28 upcoming half marathons found · 1 with finish-time stats
San Francisco running is a study in contrasts that you feel in your legs before you see on a map. The Embarcadero gives you flat, fast bayfront miles; Golden Gate Park offers a sprawling mix of paved and dirt paths anchored by the track at Kezar Stadium; and the city's famous hills are never far away. The mild climate means no race is really off-season here.
The race calendar here leans heavily toward themed, multi-distance events where you pick your distance on the day and a shirt comes with the entry. That format shapes the whole local half marathon scene, and knowing it helps you set expectations before you sign up.

Is a San Francisco half marathon a good first half marathon?
The format here helps: most events offer the 5K, 10K, and half marathon on the same day, so you can step up or step back depending on how training goes. There are no published finish-time results for these races, so we cannot tell you what pace the field runs, but the multi-distance structure means you are unlikely to be the only person finding their footing at the distance.
How themed are these races - are they serious competitions or more casual?
