WATCH: Thomas Barr's post-race interview following heroic win is just brilliant

One of the nicest things you'll see today...

We've seen the many different facets of sport over the last couple of days. The wonderful spirit of the GAA, the disappointment and anger of poor decisions in boxing and now the absolute jubilation of performing to your potential and earning your reward.

Thomas Barr absolutely smashed the field in his 400m hurdle semi-final early this morning to earn himself a spot in the final tomorrow.

While the O'Donovan brothers became famous for their wacky interviews, what we love about Barr's interview is the pure unbridled joy he has for going out and performing on the biggest stage.

Moments like these are what athletes train their whole lives for and the passion and elation on Thomas Barr's face is something to be remembered...

"I don't know. I really don't know. It hasn't sunk in. I'm just really delighted, because again, like yesterday, it could have gone either way," Barr said.

"I felt really good in warm-ups. I felt really relaxed and pumped. You know, yesterday I was a lot more nervous because I was in the unknown. I had only run 50 point in Amsterdam and I wasn't sure when I came out here whether I was a 50 point or a 49 or a 48. I just completely skipped 49 and straight down to 48, and low 48 today.

"I'm ecstatic, thrilled and I can't wait for the final. I kept telling myself that this is wide open, and it's still wide open," he added.
