The Fundació d'Esclerosis Múltiple (Multiple Sclerosis Foundation) initiated in 1994 this act of citizen participation in support of the investigation of Multiple Sclerosis. It consists of literally getting wet and to swim in any of the 30 points that will be in Mallorca (one of them will be the beach of Es Port de la Colònia de Sant Jordi from 11:00 to 14:00).
The goal is to overcome the record achieved in 2016, when more than 1,800 people swam more than 1,086,165 meters on the Mallorcan coast.
