Andrew Coscoran produced the standout performance on day two of the National Indoor Championships by blitzing the 14-year-old 1,500 metres championship record and thereby underlining a season of breakthrough performances on the American indoor circuit with his first national senior title.

In a fast-paced race from the start, the 23-year-old from Balbriggan got the better of Raheny's Brian Fay over the final 200 to win in three minutes 41.76 seconds with the 21-year-old Raheny man also inside the old record with his silver medal performance in three minutes 43.13 seconds.

On a day of compelling duels in the men's middle-distances, John Travers successfully defended his 3,000 metres title in an absorbing last lap duel with Dundrum’s Hiko Tonosa to win in eight minutes 00.96 seconds.

The men's 800 was no slouch of a race either as Mark English sat on the strong pace of Zak Curran before the Donegal man powered easily to victory in one minute 49.09 seconds.

The men's 400 was surprisingly won by Cathal Crosbie of Ennis Track Club in 47.93 seconds from Andrew Mellon, with former European finalist Brian Gregan back in third place, winning a championship bronze after a two-year long injury-enforced lay-off.

The men's 60 metres which was contested for the Craig Lynch Cup was won by an emotional Dean Adams in 6.74 seconds. Lynch, an Irish senior international sprinter, was tragically killed in a car crash last September.

The women's 60 metres was an utterly stacked race in terms of Irish sprinting talent with Ciara Neville getting up in the last 10 metres to get the better of sisters Joan and Phil Healy who were second and third respectively. Neville equalled her Under-23 Irish record of 7.30 seconds in the process.

Sophie Becker just got the better of Sharlene Mawdsley in a fine 400 metres duel winning in 53.76, while European Under-23 medallist Nadia Power was a gun-to-tape winner of the women's 800 in two minutes 6.26 seconds.

Sarah Buggy added the women's triple jump gold to her long jump gold from Saturday, while there was 1,500 metre success for Louise Shanahan and sprint hurdles win for Sarah Quinn and Ger O’Donnell.
