BEN NEVIS — Catherine, Princess of Wales, completed the National Three Peaks Challenge within a 24-hour period to raise funds and awareness for the Royal Marsden Cancer Charity. Kensington Palace stated that she is the first member of the royal family to complete this challenge.

The Princess of Wales climbed Ben Nevis, Scafell Pike, and Snowdon as part of the challenge. She began the endeavor on a Saturday evening. During the challenge, she trekked for 23 miles and achieved a total ascent of more than 10,000 feet. She also drove 462 miles between the locations.

The Princess of Wales carried out the challenge solo, with support from Mountain Rescue en route. At the conclusion of the challenge, she was greeted by the Prince of Wales, Prince George, Princess Charlotte, Prince Louis, Carole Middleton, Michael Middleton, and James Middleton.

"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," the Princess of Wales stated. She received a diagnosis of an undisclosed form of cancer in early 2024 and underwent chemotherapy. In January 2025, she announced she was in remission.

"Through this challenge, I want to raise awareness for the deeper impact of serious illness and the importance of holistic healthcare," she added. The Royal Marsden Cancer Charity launched a fundraising page at royalmarsden.org/princessofwales. The Prince and Princess of Wales are joint patrons of the Royal Marsden NHS Foundation Trust.

Why It Matters

The Princess of Wales undertook the National Three Peaks Challenge to generate funds and awareness for the Royal Marsden Cancer Charity. Her participation marks the first time a member of the royal family has completed this specific challenge. Her personal experience with a cancer diagnosis in early 2024, followed by chemotherapy and an announcement of remission in January 2025, provides direct context for her advocacy. The Royal Marsden Cancer Charity has established a fundraising page to support its work, which includes the care provided at the Royal Marsden hospital in Chelsea where the Princess of Wales received treatment.
