O’Brien & Cornyn Win 2025 Duathlon National Champs
Over 200 athletes arrived at University of Limerick this morning to take part in the 2025 National Duathlon Championships, hosted this year by Limerick Triathlon Club.
The morning was dry and bright with low wind and low temperatures, good conditions for a race around the University of Limerick Campus. Stacked fields in both the men’s and women’s events made for some amazing racing across the morning.
There are still plenty of duathlons to take part in this season, if you would like to give it a go check out our Race Calendar at the link below.

cornyn wins men's national championship
Coming off the first 4 kilometre run, a chase pack containing Leo Corry, Mathys Bocquet, Christopher Horgan, Michael Bruton and Isaac Kerr followed Niall Cornyn onto the bike at a gap of 44 seconds. Usual contenders Enda Bagnall and Dave Higgins a further 15 seconds back.
Out on the flat and fast bike course, Dave Higgins put in the fastest split of the day to pull back some time and close the gap, heading onto the second run in silver position, followed by Mathys Bocquet less than 10 seconds behind.
The battle to complete the podium came down to the last 3.6 kilometres where Predator TC’s Bocquet, currently training at the National Triathlon Centre UL, overtook Dave Higgins. On the second lap Michael Bruton moved into bronze position to secure the final step on the podium.

Niall Cornyn is Men’s 2025 Duathlon National Champion. Predator Triathlon Club’s Mathys Bocquet in second and Michael Bruton third.
O'brien is 2025 women's national champ
Judging by the start list the women’s race was always going to be hotly contested, and this morning’s event certainly didn’t disappoint.
Zoe Hughes lead from the start of the first run around the University of Limerick Campus, and had a 30 second lead into the first transition. Saoirse O’Brien, Megan Roberts, Aine Kinsella, Izabella Chidlow and Nessa Mangan rounded out the top six at this point.
The out and back bike course saw some movement in the field with Saoirse O’Brien, Megan Roberts and Aine Kinsella as the first three off the bike and into T2. It came right down to the final run to decide the podium places.
With two of the fastest run splits of the field (bettered only by eventual fourth placed Zoe Hughes), Aine Kinsella and Megan Roberts were in a battle for the silver and closing the gap to first placed Saoirse O’Brien at the same time. Kinsella managed to move into second on the closing lap and, in an exciting closing hundred metres just eight seconds separated the first three women.
Saoirse O’Brien from Piranha Triathlon Club is 2025 Duathlon National Champion with a solid performance on the Limerick course this morning. Aine Kinsella in second and O’Brien’s clubmate Megan Roberts in third.
