Dozens of hardy swimmers took a very cold Christmas dip in Prague’s Vltava river on Sunday.
It was the 75th edition of the event which commemorates the life of Alfred Nikodém, who was a goldsmith and a promoter of the Spartan lifestyle.
The water and air temperatures were 3.5 and -1 degrees Celsius.
The swim took place under tight anti-virus measures, with swimmers getting tested for Covid-19 and having to wear masks when not swimming.
Swimmers from the Czech Republic, Slovakia, Poland, Germany, Britain, Austria, the USA and Russia took part in the competition.
