Welcome to Leinster Open Sea

We are a not for profit organisation working with swimming clubs to establish a summer season of open sea races in a variety of locations along the Leinster. We cater for all ages and abilities from teenagers to senior citizens and from novice swimmers to former internationals.

If you are new to Leinster Open Sea swimming, please see our information for first time swimmers. Swim races are held every weekend with an average distance of 1 mile. There are two annual major swims: the Dublin City Liffey Swim and the Dún Laoghaire Harbour Race. For more details about these swims, including race dates, entry fees and closing dates see Major Swims. For entry forms see the Downloads section.

So if you like a challenge, keeping fit and enjoy meeting people of all levels of swimming ability – we’d love to have you join us on one of our many sea swims during the summer months.
