British mountaineer Sir Chris Bonington will mark the 45th anniversary of his summit of Mount Everest in full climbing gear, to raise funds for Nepals fight against coronavirus.
The 85-year-old said that climbing the stairs in full mountain kit is much easier than climbing Mount Everest, as he was wearing a heavy rucksack weighing about 15kgs carrying oxygen and other essentials.
In 1975, the mountaineer lead the first British team to summit, after climbing the notoriously difficult south-west face of Mount Everest.
The Everest challenge will see Sir Chris climb the stairs at his home in Cumbria twenty times, in full climbing kit.
The charity, which was set up by members of the historic team is challenging mountaineers across generations to take part and climb the stairs to raise funds.
