London —
Catherine, Princess of Wales, completed Britain’s arduous Three Peaks Challenge over the weekend to support the hospital where she underwent cancer treatment two years ago.
She said she undertook the endurance challenge – which involves summitting the three highest mountains in England, Scotland and Wales within 24 hours – to support The Royal Marsden Cancer Charity, a specialist cancer center in Chelsea, west London.
“Lots of people have asked me why I’m doing this challenge,” she said in a video message, posted on Sunday. “Partly it’s personal – I’m so grateful to be here, to be strong enough to walk these hills.”
