Sir Ranulph Fiennes has been forced to abandon his effort to climb Aconcagua, the highest peak in South America, after suffering from severe back pain.
The 72-year-old had to be helicoptered from the mountain, when he was just a few hours from the summit on Monday (16/01).
Sir Ranulph was climbing the mountain as part of his attempt to become the first person to cross both the polar ice caps and climb the seven highest mountains on each continent.
His adventures raise money for the terminal illness charity Marie Curie.
To complete his Global Reach Challenge and claim a world first, he still needs to successfully climb Aconcagua in South America, Carstenz in Indonesia and Denali in North America.
Sir Ranulph has raised over £18m in total for charity and aims to raise £20m for good causes in his lifetime.
