Kate Middleton’s family will always support her.

The Princess of Wales, 44, completed the National Three Peaks Challenge in support of The Royal Marsden Cancer Charity late last month.

In a Sunday, July 5, Instagram post, Kate shared a carousel of new photos from the aftermath of her trek, when she was joined and supported by her husband, Prince William, and their three children: Prince George, 12, Princess Charlotte, 11, and Prince Louis, 8.

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

A first photo shows Kate hugging William, 44, while dressed in her athletic wear. A follow-up image shows Kate posing with her three kids. Prince George just about towers over his mother in the snapshot.

The third and fourth images show Kate and William with their three kids, while the next shows Kate having a bonding moment with daughter Charlotte. In the background, Louis can be seen playing with a dog.

A subsequent photo shows Princess Kate hugging Charlotte, and the next sees the mother of three placing a hand on her eldest child with a warm smile.

The final image in the carousel sees Kate, William and their three kids posing with the Princess of Wales’ parents, Carole and Michael Middleton, and her brother, James Middleton.

Princess Kate participated in the challenge to support the Royal Marsden Cancer Charity’s effort to help patients facing the illness.

The London-based organization helps fund research and initiatives to benefit cancer patients during and after treatment, per its website.

In an emotional message shared on the organization’s website, Kate 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,” she added.

“Through this challenge, I want to raise awareness for the deeper impact of serious illness and the importance of holistic healthcare,” continued Kate.

The challenge Kate took part in involved climbing the highest summits in Scotland, England and Wales — Ben Nevis, Scafell Pike and Snowdon, respectively — within 24 hours.

The challenge covers 23 miles of hiking, with a total elevation gain of 10,052 feet, per ThreePeaksChallenge.uk.

Kate’s final climb was Snowdon. That is where she was met at the end by her family, Buckingham Palace previously confirmed.

The Princess of Wales announced in March 2024 that she was undergoing treatment for cancer and retreated from the public eye.

Six months later, she shared that she had completed chemotherapy, and Kate revealed that she was in remission from cancer in January 2025.
