This weekend's International Ice Mile swimming event in Lough Dan in Co Wicklow has been postponed due to treacherous weather conditions.

The event will now take place in Dublin's Clontarf Baths tomorrow.

Sixteen of the world's hardiest swimmers were due to take part in the extreme challenge, which sees participants swim one mile in open water of five degrees Celsius or less, wearing nothing more than standard swimming togs, a cap and goggles.

However, organisers issued a statement this morning saying they were postponing the event on safety grounds, as the road between Roundwood and the Lough Dan Scout Centre is impassable due to snow and ice. 

"We hate to do this but safety of all comes first," said Fergal Somerville from the Eastern Bay Swim Team, Dublin.

In a subsequent statement this afternoon, the organisers said the seawater swimming pool on Dublin's northside had "come to our rescue to allow us to use their facilities."
