The Irish Long Distance Swimming Association was formed in 1966 and held its first season of events the following year, both North and South of Ireland, at a time when open water swimming was generally and relatively unknown. From small beginnings the ILDSA over the decades has expanded greatly in size and stature and now has an International reputation. The ILDSA is affiliated to Swim Ireland and the British Long Distance Swimming Association. ILDSA is known to all the Governing Bodies of swimming worldwide.
Any swimmer wishing to be part of ILDSA can therefore also take part in all the Swim Ireland OW swim calendar throughout the country.
