There were no Irish records set in the 25m short course pool heats of the final morning of the Irish Winter Nationals at the National Aquatic Centre in Dublin.

However, Ireland's elite and performance swimmers have set up some intriguing finals when the meet moves to long course (50m) from 5.30pm this evening.

The men’s blue riband event, the 100m freestyle, looks like a battle between Jordan Sloan, his Bangor team-mate Jack McMillian, Gerry Quinn of the NCD and Callum Bain, who swims out of the University of Stirling. They are all within a second off each other after the heats.

McMillan has been the star of the meet, for which there is no medal presentations and is for Irish elite swimmers at National and Paralympic level only,

It is broken up into two distinct sessions, 25m pool heats in the morning and long course, or 50m events, in the evening.

McMillian has already taken down the 200m freestyle short and long course Irish senior records and is close to the Olympic qualification time for the event.

He looked easy and controlled this morning in the 100m freestyle and Shane Ryan’s two-year-old Irish record of 48.68 seconds could be under threat this evening in the final.

Ryan himself eased himself through the heats of his main event, the 100m backstroke, while his NCD teammate Brendan Hyland did the same in his favoured swim, the 200m butterfly.

Hyland broke his own Irish record in the 100m fly on Friday night and the Tallaght man, who says he "loves to race," will be eyeing his 1.53.19 Irish best time.

Irish international Danielle Hill had a busy morning swimming the 50m and 200m freestyle as well as the women’s 200m backstroke, and it’s not beyond the bounds of possibility that the 21-year-old from Larne could win all three events this evening.

Niamh Coyne, the 2018 Youth Olympics silver medallist, is the top qualifier for her main discipline, the women’s 100m breaststroke, while Irish Paralympians Ellen Keane and Nicole Turner will compete in the final of the same event this evening.

The final session of the Irish Winter Meet is under way at 5.30pm this evening.
