An 11-year-old boy from Liverpool has won the Pride of Britain Young Fundraiser of the Year Award, it has just been revealed.
George Mathias has raised more than £30,000 to say thank you to Alder Hey Children's Hospital for saving his little brother's life.
His little brother James was born seven weeks premature, spent five days in a coma and was close to death. Thanks to the staff at Alder Hey hospital in Liverpool, he made a full recovery and is now a happy and healthy six-year-old.
George was so grateful, he wanted to find a way to help the hospital treat other children. His dad Richard told him if he came up with an idea, he'd help make it happen.
George decided to run a mile for every month James had been alive, thanks to the doctors and nurses at Alder Hey.
But after reaching that goal, he didn't stop. George is now on his 83rd mile and aiming for 100. That's the equivalent of more than of three marathons.
So far George has raised over £32,000 in sponsorship and from auctioning off signed t-shirts he has received from well-known supporters including John Bishop and Steven Gerrard.
The first £25,000 has already been used to buy a specially-heated cot for premature babies in the Special Care Baby Unit.
