Stephen Scullion enjoyed a record-breaking run along the Antrim Coast, finishing fourth in the P&O Ferries-sponsored half-marathon, which was won by Olympic gold medallist Mo Farah.
Belfast runner Scullion's time of 61mins 08secs proved the fastest ever run by a Northern Irish athlete along a flat and fast route along the scenic east coast.
Scullion's time was just 19 seconds off the Irish record of 60:49, recorded by Alistair Cragg at the New York City half-marathon in 2011. The Olympic-bound marathon runner briefly called time on his running career earlier this year, but now appears to be back on track in his quest for a medal in Tokyo next year.
Four-time Olympic gold medallist Farah swept to victory in 60 minutes 27 seconds, while veteran runner Tommy Hughes broke the over-60s world record in a time of 71:26.
It was one of the first major sporting events in Northern Ireland following the coronavirus lockdown and spectator numbers were significantly down on the tens of thousands ordinarily expected.
Saturday's redesigned course promised to be one of the flattest and fastest in the UK & Ireland, taking in many prominent landmarks and stunning scenery along the route.
Starting at the Chaine Memorial tower built in 1888, the course makes its way through Larne town before moving onto the Antrim Coast Road.
The stunning landscape was recognised by the makers of HBO's Game Of Thrones, who used the area extensively as one of their filming locations.
Turning homeward at Ballygally Castle, the course offers one of the fastest finishes to any road race.
