A MAN running a half marathon in Dublin earlier today has collapsed and died.

The 28-year-old runner - who has not been named - collapsed after 11 miles of the Dublin Race Series event and despite getting immediate medical attention at the scene he subsequently died.

It is understood he was from Dublin. The event took place in the Phoenix Park.

"The organisers of the Airtricity Dublin Race Series regret to confirm the collapse and subsequent death of a male participant in today's Half Marathon," organisers said in a statement.

The runner collapsed at around the eleven mile mark, and was aided by fellow runners and was attended to by the St. John’s Ambulance medical crew on site.

"He was then transferred by ambulance to hospital, but was later pronounced dead.

"We would like to express our sincere condolences to the family and friends of the deceased and would ask that the family's privacy is respected at this time."
