The Polar Plunge, which was due to take place this Saturday, December 10th in Rathmullan, has been postponed until the New Year.
The cancellation is because of unforeseen circumstances and an ongoing operation in the Rathmullan area.
Organisers say they would like to apologise to everyone who has helped locally in organising the event and who had signed up to do it.
A spokesman said they feel the right decision has been taken at this time.
A new date in the New Year will be confirmed.
