The golden state has a huge range of events to choose from. 5km is one of the most popular distances to race. It’s achievable for the whole family and, with a huge range of themed races, fun runs and community events, is a great day out. This shorter distance is also great for seasoned athletes to looking hone their race times.

A 10k race is a tough but doable distance for beginners looking to move up from 5k races and test themselves with a longer run.

Looking for a tougher challenge? Take on one of California's many half marathons giving you the chance to experience everything from rugged cliffs and sequoias on the pacific coast to the steep hills of San Francisco.

For the ultimate challenge, check out listings of Ultra Running events in California with plenty of tough 50 and 100 mile races available.
