Kate Middleton, the Princess of Wales and a cancer survivor, announced on Instagram that she had taken on the National Three Peaks Challenge, in which participants attempt to climb the highest mountains of England, Scotland and Wales within 24 hours, as a “chance to explore life beyond diagnosis and to give something back”.
The princess announced in March 2024 that she had been diagnosed with cancer and by January 2025, she said she was in remission. While announcing her recovery, she thanked The Royal Marsden for looking after her so well during the past year. She and her husband Prince William became patrons of the Royal Marsden Hospital at the time.
“In my new role as joint patron of The Royal Marsden, my hope is that by supporting groundbreaking research and clinical excellence, as well as promoting patient and family wellbeing, we might save many more lives, and transform the experience of all those impacted by cancer,” the princess had said at the time.
In her post on Monday, she said, “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.
