We are the heart of open water swimming in Ireland

Racing in open water takes bravery, resilience and character, and that challenge is at the core of who we are. Our swims test body and mind, rewarding every stroke with a deep sense of achievement and connection to the sea and our community.

Here, everyone is equal. We are swimmers who love open water and connecting with like-minded people. More than a race series, LOS is a community, where everyone is welcomed, encouraged and cheered on. The atmosphere at an LOS race is uniquely warm, welcoming and fun.

Join us and become part of our community.

Cold Water. Warm People.
