Jumping into freezing water for fun might require extraordinary effort, but this Superman was up to the task on Sunday.
The swimmer, dressed as the legendary superhero, was taking part in the 78th Coupe de Noel, or Christmas Cup.
This is a swimming race held in Lake Geneva in Switzerland every year on the last Sunday before Christmas. It requires participants to swim 125m in temperatures around 5 deg C.
The sporting event goes back to 1934, when it was introduced by Swiss biscuit manufacturer Rene Doria.
In the first edition of the race, only nine swimmers took part. This year, a record 1,825 participants got into the act in all manner of costumes. Some of the memorable disguises included Vikings, a Donald Trump with a cigar in his mouth and a group of seven eating fondue in a pot while swimming, reported news website Le Nouvelliste.
