John Byrne won the Donadea 50k in a time of 3:07:54 hrs on 18 February, thereby taking the title of Irish 50km Champion.
Charlotte Kearney, running her first ultramarathon, ran a time of 4:04:06 hrs to win the female competition.
The Donadea 50k is Ireland's only IAU-labelled 50km event this year and doubled as the 2012 Irish Championships. The race is also part of the 50km World Trophy series, with Byrne's winning time making him an automatic invite for the World 50km Trophy Final in October.
Among the attendees was Athletics Ireland CEO John Foley who was watching his first ultramarathon. He was very impressed by the race setting and organisation as well as the stamina of the athletes.
In a dominant display, Irish 100km international John Byrne led from start to finish to win in an impressive time of 3:07:54 ahead of Barry Minnock (3:10:43) in second place and David Simpson (3:12:12) third.
Unfortunately, last year's winner Keith Whyte was forced to withdraw due to a chest infection. However, the depth of performances was excellent, with ultra runners who specialise in distances much longer than 50km (31.1 miles) posting very good times for the 'sprint' distance of the ultrarunning world.
The female competition was won by Charlotte Kearney, who was delighted to win her first ultramarathon race in 4:04:06. The second and third finishers were Medbh Peavoy and Orna Dilworth in times of 4:31:17 and 4:37:23, respectively.
