33 upcoming Half Marathon races found · 2 with finish-time stats
San Diego running splits cleanly between two worlds: the flat, breezy waterfront miles along Mission Bay and the Pacific Beach boardwalk, and the rugged canyon and chaparral trails that open up just inland at places like Mission Trails Regional Park and Torrey Pines. Most locals learn both quickly, and the race calendar here reflects that same mix of laid-back coastal energy and genuine terrain.
The marine layer keeps coastal mornings cool and forgiving for most of the year, which means training stays consistent and race-day conditions rarely punish you. Post-run culture is baked in too, whether that lands at a beachfront cafe in Pacific Beach, a brewery near Miramar, or a running shop in North Park.

Common Questions About Running a Half Marathon in San Diego
What will it cost me to enter a half marathon in San Diego?
Entry fees here run from $30 to $59, and the most common price is $30. Four races already have a price increase scheduled, so if one of those is on your list, registering sooner will save you money.
I want a race where I can also run a shorter distance - are there options like that?
Most of the races here are multi-distance events that pair the half marathon with a 5K and 10K on the same day, so you can bring friends or family running at different levels and all show up to the same start line. Several also include a 1 Mile option.
Will I get a shirt at a San Diego half marathon?
32 of the 33 races here say they give a shirt. One race has not said anything about giveaways either way. Medal coverage is thinner: only 1 race mentions giving one, though most races simply don't publish those details.
When is the best time of year to find a half marathon in San Diego?
Fall is the busiest stretch, with 14 races between September and November, and October alone has 5. Spring is the quietest window, with only 2 races from March through May and just 1 in March specifically. If your training block peaks in late summer, there are 6 races in the June-to-August window to aim at.
