A seven-year-old boy from Warrington said he is "happy and grateful" after walking a total of 40 miles for the Liverpool children's hospital treating his cousin for cancer.
Hundreds of people cheered when Manchester United fan Harvey Goodman arrived outside Old Trafford on Sunday 2 April.
The schoolboy has already raised more than double his previous target of £10,000 for Alder Hey and his cousin Zak Mitchell.
He said: "I heard of Zak being sick so I asked his mum if I could do another charity walk from Alder Hey to Trafford.”
Harvey walked for a total of 16 hours to complete the trek.
He continued: "It was easy at the first part then it got harder and harder.
"But I knew I had to do it so I kept on going."
Zak showed his support and appreciation by walking several miles alongside him from Alder Hey in Liverpool - and embracing him when he crossed the finish line.
Harvey said the best part of doing the walk was being able to do it with his friends.
Harvey's mum, Naiomi Goodman said: "I'm so proud of Harvey. The fact that he came up with the idea himself and then was actually able to walk 40 miles, it all came together really well."
Manchester United Legend Sammy Mcllroy, members of Golborne Sports Club, the Leigh United and Leigh RUFC teams, as well as his headteacher, teachers, friends and family members joined him at various points along the way, which according to his mum Naiomi was a real boost for Harvey.
Naiomi continued: "It was a much bigger turnout than we thought.
"The amount of support from friends, family, the people that joined the walk, people that have donated, the whole of the North West have really come together to support Harvey and it's incredible." This was Harvey’s second fundraising challenge, having previously raised almost £8,500 for his school playground by walking more than 16 miles from Stockton Heath Primary School to the Manchester United stadium. He came up with this fundraising challenge himself after hearing that his cousin had been diagnosed with an aggressive form of cancer.
Zak, who is now in remission, hopes he will now be able to start working through his bucket list, including a trip to Disneyland.
Naiomi Goodman, Harvey’s mum, said, "I’m so proud of Harvey and what he has achieved for Zak and Alder Hey. “The support and encouragement he’s had over the last two days has been amazing.
"I’d like to thank everyone who has donated to his JustGiving page. He’s raised such a lot of money, which will help so many children and their families." Sammy Mcllroy, Manchester United Legend said, "What a little champion Harvey is!
"His drive and determination throughout this walk has been amazing and the fact he’s raised such a lot of money along the way is incredible."
Asked what got him through the walk, Harvey replied, "Ice cream!" Donate to Harvey’s crowdfunding page here.
