Now in its fourth year, this event brings together 1,000 women for the UK’s biggest sea swim event celebrating International Women's Day whilst fundraising for Surfers Against Sewage.
On Saturday 14 March 2026, swimmers will take to the sea simultaneously in Brighton (East Sussex) and Sandbanks, Poole (Dorset), creating a bold, colourful, and unforgettable beach spectacle. Expect laughter, courage, connection, and two epic mass-swim moments.
Run by PinkNicky, and hosted by Sea Lanes, Brighton and Land & Wave, Poole, The Big Swim is all about community, adventure, and impact.
We are asking that every swimmer will commit to one action to support or uplift women in their community, with the goal of collecting 1,000 actions.
