It WAS a tough and gruelling race, but Dublin Fire Brigade (DFB) member Brian Doyle made it over the finish line to complete his hat-trick of Ironman challenges.
Some 2,500 athletes took part in the weekend challenge, which was the first time such an event was staged in Dublin.
The course involved a 1.9km swim in Dun Laoghaire, followed by a 90km cycle through the city and out to Maynooth before a 20km run in the Phoenix Park.
DFB member Brian Doyle (48), who is a member of Dun Laoghaire fire station, was one of those who took on the mammoth challenge.
"It was a really enjoyable event and it was well-organised which made it even better. The crowds were amazing as well, which helps, especially when you're on the final leg of the run," Brian said.
The Ironman 70.3 challenge over the weekend saw him complete his "hat-trick" of Irish events, having previously completed two races in Co Galway.
"I think everyone found the water stage very tough, but the cycling route was quick. I even managed to set a personal best of five hours and 18 minutes, so it worked out well," he added.
Also taking part in the event was fellow DFB member Liz Hanley (38), who is stationed in the Dolphin's Barn area.
"It was a really enjoyable day, the water was tough alright but once I got past that it was fine.
"I sprained my ankle in earlier this year so I couldn't train as much as I would have liked. I wasn't too happy with my time of six hours and four minutes," Liz said.
However, she was delighted to race on home turf for the first time, having previously taken part in Ironman challenges in Co Galway.
"It was great to get such a response from the crowd.
"There were a lot of family and friends out supporting which definitely helps when your running a tough race like hat," she said.
