Intro Text 

IRONMAN, today announced the addition of a new event in Ireland, the IRONMAN® 70.3® Dún Laoghaire triathlon. The event is set to take place on August 19, 2018 with general registration opening November 15, 2017. This event will take the place of IRONMAN 70.3 Dublin on the 2018 calendar.

Ireland has a strong history of IRONMAN and from 2018 onwards, a new chapter will be ushered in as our coastal town of Dún Laoghaire becomes home to the country’s biggest triathlon, IRONMAN 70.3 Dún Laoghaire.


The event, which is expected to attract close to 2,000 athletes from all over the world, will take athletes through and past the most spectacular scenery in and around Dún Laoghaire. The seaside town is popular for its natural attractions, featuring miles of beautiful coastline, numerous outdoor trails and activities, along with a rich maritime and literary history.

The race features a 1.2-mile swim from Sandycove, home to the famous Martello Tower, in the clear waters of the Irish Sea in Dublin Bay, before taking athletes on a spectacular and challenging 56-mile bike course. The course travels through some of the most scenic areas in the region, including County Wicklow, home to the Wicklow Mountains National Park and its glacial lakes, rivers and abundant natural beauty. Athletes will take in stunning coastal views and weave their way through the streets of the charming seaside town for the 13.1-mile run, before finishing  with Dún Laoghaire Harbour and Dublin Bay as the backdrop.

An Cathaoirleach (Mayor) of Dún Laoghaire-Rathdown County Council, Cllr Tom Murphy, speaking on behalf of the Council said “Dún Laoghaire-Rathdown has a rich sporting heritage, a stunning location between the mountains and the sea, a high quality public realm and is perfectly suited to host a world class sporting event of the caliber of IRONMAN 70.3. I am delighted that Dún Laoghaire town and the wider county will be the location for the event. All competitors can be sure of a fantastic experience and a very warm welcome.”
