Catherine was diagnosed with an unspecified form of cancer in early 2024 and underwent chemotherapy treatment. She announced she was in remission in January 2025.
She was treated at the Royal Marsden Hospital in Chelsea, West London. The Royal Marsden cancer charity has set up a fundraising page at royalmarsden.org/princessofwales for donations.
She completed the challenge alone, with support from Mountain Rescue along the way, and was greeted at the end by the Prince of Wales and their children, Prince George, Princess Charlotte and Prince Louis, as well as her parents, Carole and Michael Middleton, and her brother, James Middleton.
Kensington Palace said it is believed to be a royal first, with the princess being the first member of the royal family to complete the challenge.
Catherine was seen smiling at the summit of Ben Nevis on Saturday evening. She wrote that she took on the National Three Peaks Challenge not only as a physical effort but as a way to explore life after diagnosis and give something back.
