The MOSC benefits the Montauk Playhouse Community Center Foundation in its efforts to build a Cultural Arts and Aquatic Center.

The MOSC offers three distance categories for swimmers of all ages and abilities. The race moves along Montauk’s scenic coastline and concludes at the world-famous Ditch Plains Beach. Over 200 participants and supporters enjoy a post-swim breakfast.

“Giving back to your community is so important. When you give to nonprofits all over the country, you get to see some results, but when you give to a nonprofit in your town, you get to live the results. You get to use the facilities and see how happy people are when they come to the Playhouse.”
