It has been a tradition on the north Norfolk coast for more than 30 years with more than 400 people running into the sea for a Boxing Day dip
The event is organised by the North Norfolk Beach Runners and raises money for a different charity each year.
This year they picked the Norwich and central Norfolk branch of the mental health charity MIND, following the death earlier this year of Nyall Brown, one of the regular beach runners.
Over the last 30 years the event has grown in size, this year the dip had to be spread out over two sections of the beach to the east of the town's iconic pier
An estimated crowd of 3,000 turned out at 11am to watch the spectacle, while Cromer Coastguards, Cromer RNLI and St John Ambulance were all on standby to make sure the event was safe.
The sea temperature in the minutes before the dip was 4.2 degrees
