Laura Graham from Kilkeel was best Irish runner in the 2016 Dublin Marathon

A County Down mother-of-four was a surprise winner of the Irish marathon championship, run as part of Sunday's Dublin Marathon.

Laura Graham from Kilkeel, who finished 10th overall, crossed the line in 2:41.53.

The 30-year-old was over three minutes clear of silver medal winner Caitriona Jennings.

Donegal woman Jennings posted a time of 2:44.59, with last year's national champion Pauline Curley taking bronze.

Graham, who has competed in just five marathons before, said: "I only first did a marathon because my dad had a heart attack.

"I still don't think I am good enough to be an elite athlete.

"I knew I had to go steady and think smart for a change, because I didn't do that in London last year."

Charity fundraiser Pat O'Loughlin, 79, completed his 36th Dublin Marathon on Sunday - a record in terms of runners from Northern Ireland.

The Castlederg man, who turns 80 in December, crossed the line in 6:47.
