Swim Routes

The Channel Islands are a chain of eight islands off the coast of Southern California.

The SBCSA is the official governing body for marathon swims in the Channel Islands region (except swims between Catalina Island and the mainland, and swims around Catalina Island, which are governed by the Catalina Channel Swimming Federation).
