Londoners dive into cold waters on Christmas Day

Dozens of Londoners plunged into the cool waters of Hyde Park's The Serpentine lake on Sunday for an annual Christmas Day swim.

The Serpentine Swimming Club hosts the Peter Pan Cup every year on December 25, which sees swimmers of all ages take part in a 100 yard swim. Despite water temperatures of about 4-5 degrees Celsius, the event has grown in popularity in recent years.
