The organisers of the Ironman triathlon in Youghal, Co Cork have announced that the event is not going ahead in 2024.
This follows the death of two competitors in August.
Canadian man Ivan Chittenden, 64, and 45-year-old Brendan Wall from Co Meath died after taking part in the competition.
Both men died in separate incidents. They were taking part in a swim section when they got into difficulty.
Athletes had complained of horrendous conditions during the sea swim part of the event.
In a statement, the US triathlon group said it will "take a hiatus" from the event next year.
It added: "Cork County and the town of Youghal has become a much-loved home for Ironman in Ireland, and the Irish triathlon community is important to us.
"This pause will allow for further healing while we spend the next year assessing the best path forward to deliver an exceptional weekend of racing once again for our athletes in one of the most passionate host communities in the world."
Supported by Cork County Council, the event is worth an estimated €20 million to the local economy and will come as a huge blow to the local community, still reeling from the deaths of the two competitors.
However, Ironman said it is committed to bringing the event back to east Cork in 2025.
"We are thankful for the support of Cork County Council and we appreciate their continued partnership and commitment as we work collectively towards bringing back the event in the strongest way possible in 2025 and beyond," it said.
It is understood that Cork County Council, which is the host sponsor of the event, was informed earlier this week of Ironman's decision.
In a statement, Cork County Council said the decision not to go ahead with the event next year "was solely a decision for Ironman".
The council said it remained "committed to continuing its relationship" with the company.
It also confirmed that it has agreed to host the event again in 2025, 2026 and 2027.
