Princess of Wales Catherine Middleton completes Britain’s “Three Peaks Challenge,” climbing Scafell Pike, Ben Nevis and Snowdon within a 24-hour period, according to posts on her official social media accounts. The three summits are described as the highest mountains in England, Scotland and Wales. The Princess, 44, says she undertakes the challenge both as a personal physical endeavour and to “give something back,” including raising awareness of the wider impact of serious illness. Multiple outlets report that she frames the undertaking as a way to mark life beyond her cancer diagnosis and recovery. The Guardian notes she is the first member of the royal family to achieve the feat, having taken it on about 18 months after cancer remission. South China Morning Post similarly reports that she is in remission after chemotherapy for an undisclosed form of cancer and that she has spoken previously about how the illness affected her and her family. The New York Post and other coverage also describe the trek as a difficult hike across the three highest peaks, with the fundraising and awareness effort tied to a cancer charity.
