Video: 'UCC from the depths of hell' - 4x400m final produces greatest finish you'll ever see
Watch a top international 4x400m race and it is highly unlikely you will see a 20-metre or even 10m lead overturned in one leg. It just doesn't happen very often.
What you are about to see is not a top international race, but it does feature an international sprinter, which may explain what happens next.
Handing over for the final leg of the women's 4x400m relay at the Irish Universities Athletics Association (IUAA) Championships on Sunday, the race looked to be as good as over with University College Dublin enjoying a 30m lead.
What happens next contains more plot twists than an Agatha Christie novel.
So fast-forward to 3 minutes in, stick your headphones in, enjoy some of the most hilariously frantic commentary you have ever heard and be amazed.
Phil Healy take an almighty big bow... once you've recovered from your face plant.
