It follows the deaths of two competitors in separate incidents at this year’s event .
64-year-old Ivan Chittenden from Canada and 45-year-old Brendan Wall from Co Meath died during the swimming portion of the race on the 20th of August.
In a statement today, Ironman organisers say Cork county and Youghal have been a much loved home for Ironman.
The statement says the pause will allow for further healing while they assess the way to deliver the event for what they have said is one of the most passionate host communities in the world.
The event was worth over €8m to the local economy and will be seen as a major blow to Youghal and East Cork.
Organisers faced criticism for allowing the swimming portion of the event to go ahead following the deaths of Ivan Chittenden and Brendan Wall, with Triathlon Ireland saying they told organisers that they would not sanction the swim before the race.
Ironman disputes this and says they were only told of the decision several hours after the swim was over.
