Endurance Grid lists 887 running races in California, from September 2026 to February 2028 across 291 cities.
The running race calendar in California is busiest in October, November, and September, with races most often in Long Beach, Los Angeles, San Diego, and Sacramento.
Organized running races are one of the most accessible entry points into endurance sports. There’s a distance for every fitness level and a community at every start line. Distances run from 1-mile fun runs and 5Ks up through the 10K, half marathon, and marathon.
Most races are timed and chip-scored, with a mass or wave start and aid stations along the course. Big-city races keep the noise going the whole way; smaller races give you long stretches where it’s just you and the miles.
