Smiling through the buckets of rain, the Princess of Wales defied the odds to prove she was ‘strong enough’ to complete the Three Peaks Challenge.
In a secret endurance test, just 17 months after announcing she was in remission from cancer, Kate took on the ‘personal’ expedition to raise money for a charity supporting others living with the disease.
The future queen climbed the highest mountains in Scotland, England and Wales – Ben Nevis, Scafell Pike and Snowdon – within 24 hours, starting on Saturday evening.
She carried out the challenge solo, supported en route by Mountain Rescue, and was greeted at the end by the Prince of Wales and her children Prince George, Princess Charlotte and Prince Louis, and her parents Carole and Michael Middleton and brother James Middleton.
Kensington Palace said they believed the expedition was a royal first, with the princess being the first member of the royal family to complete the Three Peaks.

The royal family celebrated the undertaking, with the monarchy’s official social media account posting: ‘Congratulations to The Princess of Wales.’
Kate revealed she had taken on the trek, not only as a physical endeavour but ‘to give something back’ and raise awareness of the wider impact of serious illness.
In a video released on Sunday, the princess said she had met some ‘incredible people’ living with and beyond cancer, adding: ‘I know personally how difficult that journey is.’
The princess, who was recorded speaking before she started the walk, said: ‘Lots of people have asked me why I’m doing this challenge, and partly, it’s personal.
‘I’m so grateful to be here, to be strong enough to walk these hills.
‘But, more importantly, it’s to give something back and acknowledge, really, all the incredible work going on up and down this country.’
Kate also released a picture smiling broadly at the misty summit of Ben Nevis wearing a drenched cagoule and trekking poles on her back.
The princess could be seen wearing her sapphire and diamond engagement ring, which belonged to William’s late mother Diana, Princess of Wales.
The princess wrote: ‘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 Royal Marsden is a place that holds great meaning for me and whose care and expertise are life changing for so many people.
‘Through this challenge, I want to raise awareness for the deeper impact of serious illness and the importance of holistic healthcare.’
Sharing her own experience of cancer, she spoke of how she personally understood that the illness can affect every aspect of someone’s life.
The princess added: ‘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.
‘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.’
Kate trekked for 23 miles, with a total ascent of more than 10,000 feet, and a driving distance of 462 miles between locations.
She was previously treated at the Royal Marsden Hospital in Chelsea, west London, and The Royal Marsden Cancer Charity has launched a specially designed fundraising page for people across the nation to donate.
Money raised will be used to help more people with cancer to benefit from holistic care.
The princess, who has long campaigned over the importance of spending time outdoors, wrote: “In the end, bravery isn’t just about pushing forward.
‘It is about knowing how to stay grounded, connected and present, no matter the terrain, or landscape you are walking through.
‘Together, we can stand alongside everyone navigating life with cancer, ensuring no-one faces this disease feeling unseen or unsupported.
‘Please know you are not alone.’
Kate, who signed her personal message with a “C”, also wrote of the benefit of holistic therapies.
Money raised will also support research into how holistic care can best work alongside clinical cancer treatments to help patients, with the goal of creating a blueprint for change, so the supportive care becomes a standard part of cancer treatment nationally.
Kate was diagnosed with an undisclosed form of cancer early in 2024, for which she underwent chemotherapy, and she announced she was in remission 17 months ago in January 2025.
The physical challenge marks the latest milestone for the princess, who has gradually returned to royal duties, and last month restarted her international travel with a working trip to Italy.
