Sharlene Mawdsley, Andrew Coscoran, and record-holder Bori Akinola are all in action on day two of the National Indoor Championships.
Mawdsley is highly fancied to take the final of the Women's 400 metres at the National Indoor Arena later.
Coscoran faces a tough field including Darragh McElhinney and Nick Griggs in the Men's 1500 metre final.
Akinola will look to go back to back in the final of the 60 metres this afternoon.
Yesterday, there were wins for Olympians Sarah Lavin and Sophie Becker in the Women's 60 metre hurdles and 200 metres respectively.
