Race Venue and Course

Starting with a rolling start, the 750m swim took competitors downstream along the River Suir, before turning into a narrow channel leading to the swim exit at Suir Island.

The bike course headed left out of transition onto a largely fast and flat route, with one short climb at Knocklofty Hill before returning to town.

The run course followed the scenic Blueway route along the river, passing under the historic stone arches before finishing under the Triathlon Ireland arch at New Quay!
