It promises to be an action-packed weekend at the GloHealth Senior Track and Field Championships, with several top Irish stars still seeking to secure the qualification times needed for a place in the squad for next month's European Championships in Zurich.
The men's 15-hundred metres is one of the races to look out for, with Paul Robinson, Ciaran O'Lionaird and David McCarthy among the athletes going head-to-head.
The opening race of the day in Santry will also feature one of Ireland's leading European medal hopes when Thomas Barr lines-up in the men's 400m Hurdles at 20-past two.
