Catherine, the Princess of Wales, successfully completed the National Three Peaks Challenge on Sunday, June 28, 2026, climbing the tallest mountains in Scotland, England, and Wales within 24 hours to raise funds for the hospital that treated her cancer.
The 44-year-old royal undertook the 23-mile solo trek across Ben Nevis, Scafell Pike, and Yr Wyddfa, climbing a total of 3,064 feet and traveling 462 miles between locations with support from Mountain Rescue and a Kensington Palace driving team.

Upon completing the final peak in Wales, she was greeted by her husband Prince William, their three children, her parents, and her brother, marking her continued return to public life after announcing she was in remission in early 2025.
The endurance event sought to raise money and awareness for holistic support services at The Royal Marsden Cancer Charity, for which the Prince and Princess of Wales serve as joint patrons.
"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," Catherine said.
She emphasized that the journey extends far beyond medical treatments. "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, and that the journey through and beyond treatment requires more than medicine alone," she said.
