Little Freddie Scratchley put up with aching feet to complete a two-mile welly walk to raise £1,000 for his friends at Devizes Opportunity Centre.
Freddie, five, told his mum Jade Elliott he wanted to help our Give Us A Chance appeal when she told him the nursery he used to attend needed money.
He and a small group of friends and family set out on a two-mile cross-country walk from Worton back to his home in Potterne.
Miss Elliott said: “He did really well. He did complain about his feet aching a bit but he kept going.”
It was a remarkable feat for Freddie, who celebrated his fifth birthday the day after the walk, as he was born ten weeks early and was later diagnosed with autism.
He was referred to the opportunity centre when he was two-and-a-half and still could not speak.
Miss Elliott, 26, and her partner Gary Scratchley of Blackberry Lane, who have two other sons Liam, seven, and Billy, 16 months, are still busy collecting sponsorship money.
She said: “It is going to be around £1,000, which is tremendous.
“I am so proud of Freddie. We had some birthday tea and cake to celebrate when we got home after the walk.”
