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 50Mile/50K provides you a first rate, up-close and personal experience of one of California's natural jewels in trail running across Catalina Island. In between you simply have to run the entire length of the island - and back!
Experience some of the sports great volunteers and aid stations during your run.
