It’s springtime and the time has come to put the planks up in the cellar, all the snowsport freaks finish their season in La Clusaz partying around one last descent: the challenge of the impossible run. The Defi Foly remains the most popular water slide event of the winter, where 150 participants from all over the alps meet around the Confins lake which is 8 degrees. The tent is put up, everybody gathers around the fire and early in the morning everybody throws themselves at 100 kilometres an hour down the slope which has been made especially so that participants can slide as far as possible on the water and possibly coming out the other side unscathed.
