Welcome to the home of 3 Rock Triathlon Club. 3 Rock is one of the newest and fastest growing Triathlon Clubs in Ireland. Founded in 2008 we cater for all budding Triathletes from the complete novice to the elite and the social. We are based in South Dublin - North Wicklow with our training based around some of Irelands best venues - Wicklow Mountains, Forty Foot etc. Our fast growing reputation as one of the most social and fun clubs within the greater Dublin area capped with our high quality coaching and club competitive spirit makes 3 Rock "Solid as a Rock" - it does help that we also dont charge a membership fee thanks to our great sponsors - all we ask is that all new members join Triathlon Ireland.
