Catherine, 44, revealed in a message on social media that she had successfully taken on the trek “to give something back” and raise awareness of the wider impact of serious illness, after being diagnosed with an undisclosed form of cancer early in 2024 and announcing she was in remission in January 2025.

She climbed the highest mountains in Scotland, England and Wales—Ben Nevis, Scafell Pike and Snowdon—within 24 hours after starting on Saturday evening, and she was treated for cancer at the Royal Marsden hospital in Chelsea, west London.

The Royal Marsden cancer charity launched a specially designed fundraising page for people across the nation to donate at royalmarsden.org/princessofwales, and the princess carried out the challenge solo, supported en route by Mountain Rescue.

At the end of the trek, she was greeted by the Prince of Wales and their children, Prince George, Princess Charlotte and Prince Louis, along with her parents, Carole and Michael Middleton, and brother, James Middleton.

In her written message, Catherine said, “I have taken on the National Three Peaks Challenge, not simply as a physical endeavour but as a chance to explore life beyond diagnosis and to give something back.”

She added that “Every year, hundreds of thousands of people in this country hear the words no one wants to hear,” describing how “What follows is a path that tests every part of who we are: physically, emotionally, psychologically and spiritually.”

The Independent said she tackled the challenge solo with support from Mountain Rescue teams along the route, and it described her as being met at the finish by the Prince of Wales, her children Prince George, Princess Charlotte and Prince Louis, and her parents Carole and Michael Middleton and brother James Middleton.

In a separate message, she told supporters, “Together, we can stand alongside everyone navigating life with cancer, ensuring no one faces this disease feeling unseen or unsupported,” and she also wrote “Please know you are not alone.”

Dame Cally Palmer, chief executive of The Royal Marsden NHS Foundation Trust, said the princess’s commitment “stems from a deep empathy for those facing similar challenges” and that the support would “make a difference to the lives of so many cancer patients and their families.”

The fundraising effort is tied to The Royal Marsden Cancer Charity’s specially designed fundraising page, with money raised described as being used to help more people with cancer benefit from holistic care.

Catherine said she wanted to raise awareness for “the deeper impact of serious illness and the importance of holistic healthcare,” and she wrote that “We have an opportunity to reshape what the future of holistic cancer care looks like.”

The Independent reported that money raised will also support research into how holistic care can best work alongside clinical cancer treatments, with the goal of creating a “blueprint for change” so supportive care becomes a standard part of cancer treatment nationally.

In the same context, the Guardian said the Royal Marsden cancer charity launched the fundraising page for people across the nation to donate at royalmarsden.org/princessofwales, linking the trek’s completion to the charity’s drive for public contributions.

The Guardian also quoted Catherine’s message that “Through this challenge, I want to raise awareness for the deeper impact of serious illness and the importance of holistic healthcare,” framing the Three Peaks effort as both personal and charitable.
