The country's most famous bridge will be transformed into an unlikely diving arena tomorrow as dozens of swimmers plunged into the River Liffey in the centre of Dublin.
Dressed in togs and plastic caps, more than 50 swimmers will dive from O'Connell Bridge into the murky waters below to raise money for cystic fibrosis sufferers.
The annual spectacle dates back 27 years and was started by Dubliner Robert Clarke, who has lost three of his four children to the disease.
The 92nd Dublin Liffey Swim takes place tomorrow the 18th of August starting with the mens race at 11.15am
Are you brave enough to tackle the cold waters?
