Pictured: John O'Regan and Deirdre Finn
Kildare man John O'Regan set a new Belfast track record of 212.975km (132 miles) as he was crowned Irish champion by winning the Belfast 24-hour race.
O'Regan's distance beat the 127 miles set by last year's inaugural race winner Fermanagh man Thomas Maguire.
With Maguire dropping out after 16 hours with a torn quad muscle, Madrid-based Belfast man Eddie Gallen finished second with 205.375km (127 miles).
Tipperary native Deirdre Finn was first woman finisher as she produced 181.143km (112 miles) which left her sixth overall.
Limerick man Michael Cunningham, 46, set the early pace at the Mary Peters Track as he covered the opening marathon distance of 26.2 miles in three and half hours.
However, O'Regan, 41, moved into the lead by half distance and he went through the 100-mile barrier in 16:41:12 hrs.
O'Regan stayed on the track round-the-clock in the Energia sponsored race as did 48-year-old runner-up Gallen.
However, performance of the race came arguably from women's winner Finn who added 22 miles to last year's best female time set by Lynne Hanna. She passed though 100 miles in 19:52:17 hrs en route.
Race director Ed Smith spoke of the "true heroics" produced at Mary Peters Track.
"It's mind over matter stuff. And, the miles covered were amazing - especially with a very cold night and a very hot day to cope with. Well done to them all," added Smith.
