Sir Mo Farah the star in Larne for Antrim Coast meeting
Four men had gone clear by half distance with quadruple Olympic champion Farah, British 5,000 gold medallist Marc Scott, former Armagh winner Ben Connor and local star Stephen Scullion clear of a group including another home hope in Kevin Seaward.
Farah and Scott then moved away, with Farah breaking as they came onto the promenade. He came home strongly, showing no signs of fatigue after his World Hour record to cross the line in an Allcomers record of 60:27.
Scott, in his first-ever Half Marathon, ran 60:39 with Connor 60:55 and Scullion smashing the Northern Ireland record in fourth with 61:08.
Kevin Seaward was a brilliant fifth in 63:05, Chris Madden came 18th with Conan McCaughey 21st.
Tommy Hughes followed his World O60 10-miles record last week with another new standard of 71:09, coming over the line in great shape.
Lily Partridge - the women’s favourite - and Sam Harrison went through half distance 14 seconds ahead of Clara Evans and Becky Briggs and it was Partridge who took the honours by 22 seconds from Harrison, with Evans and Briggs following.
The winning time of 71:36 was another Allcomers record.
Jessica Craig ran impressively to set a Personal Best of 75:45 in sixth.
Gladys Ganiel came 10th and Ciara Toner 12th.
Farah was full of praise for the course, welcome and support.
He now heads for a pacemaker role at the London Marathon in Hyde Park.
