Join us and be solid as a rock!

Founded originally in the 1980s by a small crew of committed triathletes including our club chairman Eamonn Tilley, and re-formed in 2008 in the Greystones/Kilcoole area, we cater for athletes at all levels, from the complete novice to the elite and the social.

Our members come from the Southeast Dublin and Northeast Wicklow areas, and we train in some of Ireland's best facilities (e.g., Charlesland athletics track) and on some of its most scenic and challenging terrain.

Please address all questions about club membership, race entries etc. to:  threerocktriathlon@live.ie. - We are also on facebook under "ThreeRock" triathlon.
