Tobias had been planning a sponsored 1 kilometer (0.6 mile) walk around a local park last month, but was unable to go ahead with it because of coronavirus lockdown restrictions.
“Then I heard about Captain Tom and I thought why don’t I use my walker to try to complete a marathon by walking up and down my street every day,” he said in a video ahead of the marathon, admitting it would be a “ginormous challenge.”
At the beginning of lockdown, Tobias could walk a maximum of 50 meters (164 feet) a day, but as he grew closer to completing his challenge — which took him 70 days, according to the PA Media news agency — he was walking up to 750 meters (half a mile) a day.
“I can’t believe I completed a marathon, it’s just awesome,” he told Sky News.
He said: “Every bit of it has been totally awesome.
“I love it when my neighbors clap and cheer for me. I’m getting stronger and stronger every day. It’s such a good feeling.”
So far, Tobias has raised over £81,600 ($100,700) — £50,000 more than his original target of £30,000 for Sheffield Children’s Hospital and Paces School, a school that supports children and adults with neurological conditions, including Tobias.
Tobias’ mother, Ruth Garbutt, said they were going to continue walking and were aiming to reach 50 kilometers (31 miles), PA Media reported.
“I’m so, so pleased that he’s completed his marathon. He’s done really well. He’s tried so hard all the way through. He’s really achieved a massive goal,” she said, according to PA.
“I’m bursting with pride for my little boy. He’s just magnificent.”
