3D is home to over 150 members, ranging from athletes who have just learnt to swim & want to complete their first sprint triathlon, to National Series winners & contenders, to sub 9.30 Ironmen. We welcome all.

3D's training schedule covers the three elements of triathlon plus strength & conditioning, specific open water sessions, transition practice and nutrition workshops. 3D's training changes from race season (May to September) to off season (October to about May). 

Before joining you are very welcome to attend a training session for free to see if 3D is for you. Please email This email address is being protected from spambots. You need JavaScript enabled to view it.  and we will make sure you get a friendly welcome at your try out session.

Other things to consider

  • 3D has created an associated Masters Swim Club "3D Masters". This year 3D Masters Swimmers took part in the Leinster Open Water League & qualified for the Liffey Swim (and did the club proud:)). 

  • 3D has a Marathon Club, where members wishing to race Dublin City Marathon, can receive specialised marathon coaching & join specific training groups. 

Does the Club have social activities?

3D members are a very sociable & fun crew. Please join the 3D group on Facebook and you will get an instant update on what 3D members are up to.

Club members have frequent informal gatherings: to "celebrate" the first long bike of January and the first grimly cold Open Water session in May, to meet & greet newbies in January. After Saturday running & Sunday long spins it's now tradition to have tea & cake in the Visitors Centre in the Phoenix Park. The non Lycra social scene starts with the October AGM, the November "End of Year" Party (club subsidised meal out & awards usually attended by c80 members). Christmas then has the "12 Pubs" outing for members to catch up before the Christmas break.


New Members

3D & Triathlon Ireland 2016 membership opens on the 19th October, 2015.  Membership will cover you for the remainder of 2015 and all of 2016.

For insurance cover, members of 3D must also be members of Triathlon Ireland. The membership form & payment is via Triathlon Ireland through their website

During that process the option of selecting a club will be offered, select 3D Tri.  The current cost for joining is: 

  • Club Membership 65
  • TI membership (racing) 60
  • TI membership (non racing) 20
  • Student 30

So an adult member who intends to race in 2016 will pay €125.


Current Members

3D & Triathlon Ireland membership does not expire until end of 2015 so you don't need to renew until 1st January 2016.  Please make sure you renew before attending 2016 club sessions: we can't let you attend without insurance!


Are there responsibilities involved in being a club member?

3D is a purely voluntary club, run by members for members. There is a club committee with the usual range of club officers and race committees for the 3D Winter Aquathlon series and 3D Sprint Triathlon. It's great when members get involved: we need your help plus it's a great way to get to know people.

When club races go ahead, members are expected to give up about 4 hours on a Sunday & marshal. It's not a big ask. It's usually good fun. If you race you kind of owe it to all those marshals out there on other windswept courses to return the favour.
