A 90-year-old woman attempting to climb the equivalent of a Highland mountain on her staircase has smashed her target to raise £10,000 for the NHS and a hospice, with her total now hitting £100,000.
Margaret Payne plans to climb the height of Suilven - 2,398ft - by making 282 trips upstairs.
It comes as 99-year-old war veteran, Captain Thomas Moore is winning hearts across the UK and has raised £18 million for the NHS by walking his garden 100 times.
Mrs Payne said Captain Moore inspired her to take on the climb.
She started the challenge on Easter Sunday and expects it will take her around two months to complete.
Mrs Payne had raised £1,800 on her Virgin Money Giving page by Wednesday but by Friday morning she had raised more than £38,000. By the afternoon, it had hit £100,000.
The challenge is her way of saying thank you to NHS and hospice staff who took care of her late husband Jim.
She said: "I think it's amazing, I wasn't expecting anything like it - 10,000 thank yous.
"I think it's brilliant of them all and I feel the NHS really deserve it.
"They have been amazing, each day they are risking their lives."
Mrs Payne added: "My husband died at Christmas, and the NHS were absolutely wonderful. So it was a way of saying thank you."
After seeing the efforts of Capt Moore, Mrs Payne was inspired to do something to give back to health staff.
Mrs Payne, who lives in Ardvar, Sutherland, said she was never a hillwalker, having lived with knee problems since she was 12.
Her true passion was fishing and she said she would walk miles to reach the best spots.
"I do walk around the garden, every nice day", Mrs Payne said.
"I'm always afraid of being blown over now so when it's windy I daren't go.
"Our house stands rather high, facing the prevailing winds so it asks for it a bit."
Mrs Payne takes on the stair-climbing challenge several times throughout the day, starting in the morning once she is ready and finishing in the late afternoon.
Nicky McArthur, her daughter, believes that the fresh air of north-west Scotland has helped keep her mother healthy, adding: "Mum is still incredibly active. She is an avid reader and crossword-doer. I think part of it is just staying interested in life."
