Two men who died during an Ironman event in Co. Cork yesterday have been named.
65-year-old Ivan Chittenden from Toronto in Canada was holidaying in Ireland when he decided to take part in the event in Youghal.
Brendan Wall, aged 44 was, originally from Co. Meath but was living in Solihull in England.
Post mortems will take place on the bodies of both men today.
Ralph Riegel, Southern Correspondent with the Irish Independent, says the results will be crucial to the investigation.
"I think the findings of those post mortem examinations are going to be critical.
"At this stage, it's believed that there may have been personal medical emergencies were a key factor in both deaths.
"If that is the case, it's obviously going to direct, I think, where the safety investigation goes."
