The biggest duathlon series in Ireland is back for summer 2017!

The Phoenix Park Duathlon Series, sponsored by Mason Hayes & Curran, is returning to Dublin’s Phoenix Park with our next mid-week races on Wednesday evenings:

  • 7th June 2017 (Wednesday)  – adult & junior
  • 5th July 2017 (Wednesday)  – adult & junior

NEW for June: You will enjoy racing on closed roads in Dublin’s iconic Phoenix Park. Our race has some important changes since April, including a new mount/dismount line, an improved transition layout, a junior race beforehand, a free neck warmer/buff for everyone and a later start time.

The race course is based close to the Papal Cross in the Phoenix Park. Read more, view maps & watch videos of the course on the Course Description page.

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.
