A runner who died after the Cardiff Half Marathon was treated “instantly” after an incident at the finish line, the race organiser has said.
Run 4 Wales chief executive Matt Newman said the man’s family was being supported.
The runner was seen by a medical emergency team on the course then taken to University Hospital of Wales where he died.
“Everyone at Run 4 Wales is devastated,” Mr Newman said.
“It’s terribly sad news… not just our thoughts but our support is with the family at this really difficult time,” he told BBC Radio Wales.
“It was an incident at the finish line, yards away from the primary medical centre so it was an instant response.”
In 2018 Ben McDonald, 25, from Cardiff, and Dean Fletcher, 32, from Exeter, went into cardiac arrest and died after crossing the finishing line at the half marathon within three minutes of each other.
No inquests took place, and a coroner’s investigation found the pair died of natural causes.
