Roads will be closed for our races, making this is a great event for beginners and people who want to push towards the podium. We’re offering a super mix of sports-related prizes and the race will be timed electronically with results & photos going online shortly after everyone crosses the line. This is a 100% club-run event. It is fully sanctioned by Triathlon Ireland, and all levels of athlete are welcome and all proceeds go back to funding club activities.
