John Griffin, from Shoreham, England, aims to raise £245,000 for charity after taking on the 'Climb Everest At Home' challenge.
Griffin, aged 53, live-streamed walking up his stairs approximately 1,361 times, completing more than 50,000 steps in four days - the equivalent of climbing Mount Everest.
More than £1,400 has already been donated. The funds will go to Trussell Trust, a non-profit which supports a nationwide network of food banks in the UK.
'A perilous situation'
On his fundraiser page, Griffin, who has delayed the opening of his vegan takeaway business due to the Coronavirus (COVID 19) pandemic, said: "More people than ever will be turning to Foodbanks to feed themselves during these unprecedented times and with in-shop donations stalling you can help with a cash donation.
"I was disgusted to hear that the foodbank trolly had to be removed from a local Tesco as the contents were being stolen, quite possibly by people that could afford to purchase those items. Foodbanks really need our support more than ever."
