The Castle was built during the Gothic revival period and was once home to now King Charles during a 3-day visit to Ireland.
The Castle is idyllically situated overlooking the Estate’s 1,000 acre lake (the largest privately owned lake in Europe), home to this event’s open-water swims.
Our Lough Cutra Castle event features some truly iconic courses in the West of Ireland. The weekend will host a huge range of races for all ages and abilities.
Whether you’re 9 or 90 years old, a first-timer or an elite, you can pick from our triathlon, duathlon, aquabike, aquathlon, run and swim races.
