Thomas Barr from Ferrybank Athletics Club is competing in heat 2 of the 400 metres hurdles this morning in Munich, Germany at the European Championships.
The race kicks off at 10.12 am with Thomas in action against five other athletes.
The top three from each of three heats plus the two fastest losers overall go forward to Thursday morning's semi finals.
Speaking to RTE Sport, Thomas believes he can run a personal best time in Munich.
"If I didn't think I could still run faster, I wouldn't still be running. That's the honest truth of it because last year if I'd executed the perfect race, or what I thought was the perfect race in the semi-final in Tokyo, I would have run a PB - and it would have been a big PB of 0.3 or 0.4 of a second. I hit hurdle seven and it knocked me back. This year all the markers were there that I was in PB shape coming into this season, way ahead of where I was other seasons."
"I really do think I could run a PB in Munich. If everything comes right I think I can. If not there's no reason why I can't in the next year or two."
