24 upcoming Half Marathon races 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.

We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Jul 27, 2026.
Entry fees here run from $25 to $43.05, with a typical fee of $30. One race already has a price increase scheduled, so check the registration page sooner rather than later if you have a specific event in mind.
Fall (September to November) is the busiest stretch, with 9 races. Winter (December to February) is the second busiest with 7, and summer brings 6. Spring is the quietest window, with just 1 race in March. The mild year-round climate means even winter races are genuinely runnable.
22 of the 23 races say they give a shirt. The remaining race has not published giveaway details, so we cannot say either way. None of the 23 have said they give a medal.
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.
The calendar skews strongly toward themed events - coffee, donuts, bagels, chocolate, Halloween, Oktoberfest - most from the same series, all priced at $30 and paired with a shirt. RunThrough San Francisco 5k, 10K & Half Marathon on November 7 is the one race in the lineup that sits outside that mold, and it is also the only one with a different price point.
Yes, one race around San Francisco gets you off the pavement: 1 mixes road and trail. Surfaces are not always published, so it is worth checking a specific race before you register.
