Catalina Island, Avalon CA
Saturday, January 10th, 2026
The Avalon Benefit 50 Mile/50K Run is the oldest Ultra Trail Run in California with the 50 Mile run entering its 43rd year. The 50K joined the party six years ago and instantly became a California classic in trail running traversing all of the same trails that the older run uses.
Running the Avalon Benefit 50 Mile/50K provides you a first-rate, up-close and personal experience of one of California's natural jewels in trail running across Catalina Island.
During the run, you will experience some of the sport's great volunteers and aid stations, ensuring you have the best experience possible.
