Night Train Swimmers
The Night Train Swimmers is a group of San Francisco Bay Area extreme open water swimmers who work together to improve the lives of people around the world by raising money for various non-profit organizations. This all-volunteer organization was founded in 2008 and started with a five-person relay crossing of the English Channel.
It has since grown in membership and impact each year since with marathon relay swims in the Sea of Cortez in Mexico, Lake Powell bordering the states of Arizona and to the Farallon Islands off the coast of San Francisco. Its mission is to swim for charity.
