15 MAY 2027 | LANESBOROUGH | NOT PART OF THE 2026 TRILOGY

Gaelforce Great River Swim

The Trilogy begins with the Gaelforce Great River Swim. 

Choose from four distances - 800m, 3.5km, 5.8km or 12km (marathon) - swimming downstream along the River Shannon through scenic countryside, finishing on the shores of Lough Ree. (Distances are longer for this Trilogy event, as swimmers benefit from the natural flow of the river.)

At the finish line, you’ll be welcomed with hot food and drinks, music, and plenty of craic on the riverbank - a well-earned reward for completing the first stage of your Great Swim Trilogy.
