Kate Middleton shared a rare look into her family support system in new photos shared on social media.

The Princess of Wales, 44, posted a message to her followers on Instagram on Sunday, July 5 — exactly one week after she revealed that she had secretly completed the National Three Peaks Challenge, which entails hiking Britain’s three tallest peaks in England, Scotland and Wales — to help raise funds for The Royal Marsden Cancer Charity.

“This time last week, completing the National Three Peaks Challenge. A huge thank you to everybody who has supported The Royal Marsden Cancer Charity,” Kate captioned the post.

Her message was accompanied by a series of intimate family photos taken after she descended the final summit.

In one of the photos, Kate, wearing casual red athletic shorts and a black T-shirt, can be seen hugging her husband, Prince William, 44.

Another picture shows Kate taking her daughter, Princess Charlotte, 11, into a big embrace, while others capture her chatting cheerfully with family.

In yet another photo, the Princess of Wales appears visibly emotional as she places a hand on the shoulder of her eldest child, Prince George, 12.

Kate’s parents, Carole and Michael Middleton, and her brother, James Middleton, were also there to help celebrate the major achievement.

Kate initially shared a photo of herself in full hiking gear at the summit of Ben Nevis, the highest peak in Scotland, on social media on June 28.

She accompanied the photo with a message about the realities of navigating a cancer diagnosis and her decision to complete the hiking challenge.

“Every year, hundreds of thousands of people in this country hear the words no one wants to hear,” she began in her post.

“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,” she continued.

“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 added.

Kate went on to share that she embarked on the National Three Peaks Challenge “not simply as a physical endeavor,” but “as a chance to explore life beyond diagnosis and to give something back.”

The princess, who announced that she was in remission from cancer in January 2025 after revealing her diagnosis the previous year, also explained that her participation in the challenge would help raise funds for The Royal Marsden Cancer Charity — specifically the charity’s efforts to expand access to holistic cancer care for patients across the U.K.
