T3 Triathlon Club Dublin was formed in 2008 by a bunch of people who came together to train and became friends.

T3 stands for the extra ingredient, in triathlon there are two transitions so T3 represents the focus on the social aspect of the sport and the friends made along the way.​

We are delighted to have grown to around 80 members since the club was established.  We cater for all ages and abilities with members perparing for Ironman events right down to the casual triathlete getting ready for their first sprint triathlon.
