Lough Cutra Castle Triathlon routes

All of the races at Lough Cutra Castle kick-off with a stunning open-water swim in the lake, transitioning into a bike route which takes competitors through Lough Cutra itself.

The half iron Gauntlet cycle takes in the beautiful Burren national park. The event offers not only a chance to race but a festival atmosphere with live music, dancing, children’s entertainment, retailers, and food.

The countryside surrounding Lough Cutra Castle contains evidence of a history dating back to the Irish-Celtic mythology of the Tuatha Dé Danaan.

Old churches, cells and monasteries are prolific in the area, with some of the islands on the lake containing the remnants of stone altars.
