A boy with spina bifida has raised more than £100k for the NHS in 24 hours by walking 10m with his frame.
Frank Mills, six, from Bristol, uses a wheelchair and only started walking 18 months ago.
Frank originally hoped to raise £99 for NHS Charities Together in homage to Captain Tom Moore.
His parents, Janet and Tony Mills, said he chose the amount to match Captain Tom's age.
Mrs Mills said: "His campaign has just taken off and we are very grateful to everyone who has donated."
As well as having spina bifida - a condition where a baby's spine does not develop properly in the womb - Frank was also born prematurely at 25 weeks.
He has received care from both Southmead Hospital and the Bristol Children's Hospital and wanted to raise the money as a thank-you to the NHS.
Supportive social media comments for his challenge have come in from as far afield as Australia.
Writing on Facebook, Peter James Edgar, said: "Well done young man. Tom Moore will be grateful and proud of you."
Another commentator, Peter Freeman wrote: "A 99-year-old superhero inspires a young super hero, proving you are never too old or young to do the right thing."
Christine Julian also wrote: "Wouldn't it be great if Frank and Captain Tom could meet after all this madness ends?"
Frank will continue his daily 10-metre challenge for as long as he chooses to.
