Swimming Marathon

Swimming marathon

The Poreč Dolphin Swimming Marathon is one of the most exciting sporting events on the Poreč coastline, bringing together swimmers of all ages and abilities.

Participants join primarily to challenge themselves and test their endurance. There is no single winner and time is not the main focus. The goal is to complete your chosen route, and those who need extra support can use swimming aids to help them reach the finish. The routes are suitable for both beginners and experienced swimmers.
