The Men's Race starts at 1.30pm and the Women's Race starts at 2.15pm. Every year over 200 men and 80 women enter the race which passes the Four Courts, the Ha'penny Bridge and many other famous Dublin landmarks.
This unique event has been attracting thousands of spectators for over 90 years and everyone is invited to come and support on the day.
Entries for the race are now closed. All competitors have to finish four of Swim Ireland's 'open water' swimming events.

More people are reading Afloat.ie than ever thanks to the power of the internet but we're in stormy seas because advertising revenues across the media are falling fast. Unlike many news sites, we haven't put up a paywall because we want to keep our marine journalism open.
Afloat.ie is Ireland's only full-time marine journalism team and it takes time, money and hard work to produce our content.
So you can see why we need to ask for your help.
