Gary O'Hanlon claimed victory in the men's Cork City Marathon, setting a new record for the race on the way, while Zola Flynn won the women's race.
The Clonliffe Harriers runner took the win in commanding fashion, finishing in a time of 2:21:09, just over four minutes clear of runner-up Mark Kirwan of Raheny Shamrocks, who cross the line in 2:25:17.
Speaking afterwards, O'Hanlon said: "It was a very tough race out there, I always knew there was going to be a very tough battle between the five of us that are sub 2:20 runners.
"It got tougher and tougher for everyone as the race went on but it got warmer as well. It started at thirteen degrees and it went up and up. The temperature just rose as the day went on and in the second half of the race it started really getting tough for everybody - everybody's times were slipping.
"I said to myself I've been in the Cork City Marathon four times and I was second twice and third once and I just said I had to win at some stage. I'm nearly 44 years of age so I mightn't be here next year for it - this year was the year I said I'd give it a go, especially for my eleven month old son coming to his first marathon."
The women's race was won by Sligo's Zola Flynn in a time of 2:58:05. The Calry AC athlete took a strong lead right from the start and cruised home 3:29 ahead of second placed Rachel Davies.
Like O'Hanlon, Flynn felt the warm weather make things tough for the competitors. "I'm delighted," she said. "I came fourth in Dublin last year and came here this year looking for a podium position, so to get first I'm absolutely delighted.
"It was hot, it was hard and the last few kilometres were very hard but I just dug deep and am delighted with a first. I run with a small athletics club in Sligo called Calry A.C.- there's not too many of us in the club but great to get a first for them."
With 38 different countries and 73 nationalities represented, over 8,500 individuals took part in the race.
