Terry Brady, officially the world's best uncle, is attempting to break a world record, by running the fastest marathon ever dressed as a bottle.
He's hoping to raise much needed funds for his nephew and god son Theo, who was born with a rare form of deafness.
The money raised will go towards a pioneering operation, which will enable Theo to hear for the very first time.
Terry will attempt to break the Guinness World Record in the Waterford Marathon on the 27th June.
The current time stands at 3:31:57 and was set in the 2014 London Marathon.
