The California Half Marathon Calendar is a complete simplistic listing of California half marathons. Currently the California half marathon schedule has 2019 California half marathons and 2020 California half marathons as they roll in. California half marathons 2019 & California half marathons 2020 also identify trail half marathons and walker friendly half marathons by a (T) symbol and a (W) symbol. The (T) means it is a TRUE trail half marathon (off road, switchbacks, etc) and a (W) means it is truly "official walker friendly" requiring the half marathon to allow a minimum of 18:32 mile pace, minimum 4 hours for participants to finish the 13.1 mile distance. The California half marathons 2018 should be starting to roll out soon!
The California half marathon calendar features a complete listing of San Diego half marathons, San Francisco half marathons, Los Angeles half marathons, Sacramento half marathons, San Jose half marathons, Southern California half marathons, Northern California half marathons, and many more 1/2 marathons in CA.
A half marathon is 13.1 miles (or in kilometers is a 21k). We understand sometimes there will be a slight margin of error up or down when runners run or walk any race distance, however our calendar only is a listing for true half marathons that do all they can to measure their course as an official half marathon 13.1 mile / 21k distance. Races that are not 13.1 miles, we encourage not to call their race a 1/2 marathon to lessen confusion for runners & walkers looking to participate in a true 1/2 marathon distance. Some runners don't care, but you'd be surprised how many that do.
