Popular swimming with no time or style limits - that's the way to let off steam in the water.

For 12 hours, swimming enthusiasts and professional swimmers can expend their energy as they wish at the Estavayer-le-Lac OC swimming pool. Anyone can come and swim, at any time during these 12 hours, the distance and in the style they want. There is no timekeeping. A souvenir medal will be awarded for metres swum in the 25m pool: bronze from 1,000m, silver from 5,000m, gold from 10,000m.
