The lay of the land
California runs a year-round race calendar, so there’s almost always a race near you. The calendar is busiest in October, September, and November, with races most often held in Los Angeles, San Diego, Long Beach, and Sacramento.
Races in California cover every kind of terrain — from the Pacific coastline to the Sierra Nevada, the Central Valley, and the southern deserts. That means sea-level beach 5Ks, high-country trail ultras, and flat, fast valley road races.
Conditions vary widely by region across California, so weather lives where it’s accurate — each race page shows its typical race-day high, low, and rain chance from NOAA climate normals for that venue and date.
