Average Reviews


Joe is one of the world’s most prolific open water swimmers and enjoys swimming around the world with his brother, John. He has swum over 110 documented marathon swims including 5 of the Oceans 7 Channels, the Triple Crown, Triple Crown of Stage Swims, and the Ultimate Swim A Thon which included a 10K in all 50 states in 25 days.

Zemaitis founded the Foundation for Aquatic Safety and Training (FAST) that was inspired by Braxton Bilbrey, a 7-year-old boy, who became the youngest person to swim from Alcatraz Island to the San Francisco shoreline. Motivated by Braxton’s story, over 50 swimmers ages 8 to 18 made that same 1.4 mile stretch of frigid open-water swim the following year. These competitive swimmers became the first FAST ambassadors of water safety, reaching out to the next generation of young people with the message of water safety and drowning prevention.
