The Princess of Wales completed the National Three Peaks Challenge in under 24 hours, climbing Ben Nevis, Scafell Pike, and Snowdon in a secret endurance test just 17 months after announcing she was in remission from cancer. She described the trek as a personal mission to give back and raise awareness of the wider impact of serious illness.
Secret challenge completed in 24 hours
Starting on Saturday evening, Kate climbed the highest mountains in Scotland, England, and Wales—Ben Nevis (1,345m), Scafell Pike (978m), and Snowdon (1,085m)—covering 23 miles of trekking with a total ascent of more than 10,000 feet, and driving 462 miles between locations. She was supported en route by Mountain Rescue and greeted at the finish by the Prince of Wales, her children Prince George, Princess Charlotte, and Prince Louis, and her parents Carole and Michael Middleton, along with her brother James Middleton.
Kensington Palace said they believed the expedition was a royal first, with Kate being the first member of the royal family to complete the Three Peaks. The monarchy’s official social media account posted: 'Congratulations to The Princess of Wales.'
Personal motivation and gratitude
In a video released on Sunday, Kate said: 'Lots of people have asked me why I’m doing this challenge, and 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, really, all the incredible work going on up and down this country.' She added that she had met 'incredible people' living with and beyond cancer, stating: 'I know personally how difficult that journey is.'
Kate also released a picture from the misty summit of Ben Nevis, smiling broadly while wearing a drenched cagoule and trekking poles, with her sapphire and diamond engagement ring—once belonging to Diana, Princess of Wales—visible.
Fundraising for holistic cancer care
The challenge raised funds for The Royal Marsden Cancer Charity, specifically to support holistic care for cancer patients. Kate, who was treated at the Royal Marsden Hospital in Chelsea, wrote: 'The Royal Marsden is a place that holds great meaning for me and whose care and expertise are life changing for so many people. Through this challenge, I want to raise awareness for the deeper impact of serious illness and the importance of holistic healthcare.'
Money raised will help more people with cancer benefit from holistic therapies and support research into integrating holistic care with clinical treatments, aiming to create a national blueprint for supportive care as a standard part of cancer treatment.
Kate's cancer journey and return to duties
Kate was diagnosed with an undisclosed form of cancer early in 2024 and underwent chemotherapy. She announced she was in remission 17 months ago, in January 2025. The physical challenge marks the latest milestone in her gradual return to royal duties; last month she restarted international travel with a working trip to Italy.
In her personal message, signed with a 'C', Kate reflected on the broader impact of cancer: 'Every year, hundreds of thousands of people in this country hear the words no-one wants to hear. What follows is a path that tests every part of who we are: physically, emotionally, psychologically and spiritually. The challenges ripple outwards, touching families, friendships, work and the quiet moments we spend alone with our thoughts. Cancer doesn’t just affect the body. It changes how you think and feel and profoundly affects every aspect of life. I know this personally.'
