Members of the Thong Rangers braved the elements to raise money for a young boy with cystic fybrosis.
They bounced around Didcot on spacehoppers wearing just the bare necessities for 14-year-old Tyson Lemarechal on Saturday.
Thong Ranger Clifford Oakes said: “It was cold but apart from the weather it went really well.
“We did about five miles in the end and probably raised about £500.
“Every single family who comes to us for help touches my heart.”
Tyson, from Didcot, was diagnosed with cystic fybrosis when he was three days old. The money raised will go towards a trampoline and a bike for him.
His mother Lyn said: “I am very grateful for what they have done for us. I got a bit emotional.”
