To date, there has been a very special group of individuals - 25 marathon swimmers over the age of 50 years - who have successfully swum across the Catalina Channel between Santa Catalina Island and the Southern California mainland: members of the Catalina Channel Half Century Club.

Their grit and determination are admirable at any age. These aquatic adventurers thrive in this Fountain of Youth in the Pacific Ocean and have proven that some things do get better with age.

The members of this exclusive club are listed below.

If you know of any individuals who are not listed and who are eligible join the Half Century Club in any body of water, please send information on the swimmer's name, country, official time, date and location to Open Water Source via email ( For additional information on marathon swimming records, visit the International Marathon Swimming Hall of Fame website.
