Two youngsters have raised £1,200 for Blackpool Victoria Hospital’s in-house charity in memory of their step-dad.
Brayden Camm, 13, and his nine-year-old sister Libby took part in a junior extreme assault course for Nick Wood, who died from a serious heart condition in February aged just 39.
Their mum, Kelly Abraham, said: “As soon as Nick died, they both said they wanted to do something in his memory.
“They said all along it was the right thing to do and they did really well.
“Nick would have been so proud of them. They have raised so much money and it is still coming in.”
The Junior Muckers feat, held near Lancaster in June, saw the youngsters beat a gruelling set of obstacles, including mud pits and an ice-cold plunge pool.
Lauren Colding, community fundraiser for the Blue Skies Hospital Fund, said: “It is wonderful to see Libby and Brayden doing something so brave in memory of their step-father.
“We are extremely grateful for their support and such a fantastic total, which will make such a difference to the unit.”
Brayden and Libby, of Meyler Avenue in Layton, met with heart surgeon Andrew Duncan at the hospital, who thanked them for their amazing efforts and posed for a picture with a charity t-shirt.
He added: “This is a fantastic amount of money and we are really, really grateful to Brayden and Libby.
“All the money is put back into care for cardiac patients and we will make sure it is put to good use.”
Mr Wood was diagnosed with cardiomyopathy after being admitted to hospital with a suspected blood clot after struggling with a chest infection.
He was placed in a coma but later passed away. Kelly added: “He was a well-liked person and was very popular.”
