In a remarkable display of endurance and determination, Catherine, Princess of Wales, has completed the United Kingdom’s iconic Three Peaks Challenge, climbing the highest mountains in Scotland, England, and Wales within 24 hours. The fundraising feat supports The Royal Marsden Cancer Charity, the specialist cancer center where she received treatment two years ago.
The challenge involved summitting Ben Nevis (1,345 meters), Scafell Pike (978 meters), and Mount Snowdon (1,085 meters)—a total ascent of 3,064 meters (10,052 feet). Catherine, 44, undertook the challenge alone and was greeted at the finish by her husband Prince William, their children Prince George, Princess Charlotte, and Prince Louis, as well as her parents Michael and Carole Middleton and her brother James.
In a video message released Sunday, she explained her motivation: ‘Lots of people have asked me why I’m doing this challenge. Partly it’s personal—I’m so grateful to be here, to be strong enough to walk these hills. But, more importantly, it’s to give something back and acknowledge all the incredible work going on up and down this country.’
The Princess announced her cancer diagnosis and chemotherapy treatment in March 2024, following major abdominal surgery. Nearly a year later, she revealed she was in remission and has since gradually returned to royal duties. She has become deeply involved with The Royal Marsden, and last year Kensington Palace announced she and Prince William would serve as joint patrons of the charity.
By completing the challenge, Catherine hopes to ‘explore life beyond a diagnosis,’ noting that cancer ‘changes how you think and feel and profoundly affects every aspect of life.’ She has championed holistic care that supports patients’ mental, social, spiritual, and physical wellbeing. Alongside her statement, a fundraising link was released for the public to donate to the Royal Marsden.
