The Princess of Wales, Kate Middleton, successfully completed the National Three Peaks Challenge over the weekend in an effort to raise awareness for The Royal Marsden Cancer Charity. Joined by her brother, James Middleton, and one of his dogs, the Princess undertook the challenge to shine a light on life post-cancer, following her recent remission.

On June 28, 2026, Kensington Palace announced that the Princess had summited the highest peaks in England, Scotland, and Wales—Ben Nevis, Scafell Pike, and Snowdon—within a 24-hour timeframe. The grueling challenge involves approximately 23 miles of hiking with a total elevation gain of around 10,052 feet.
A fellow hiker shared a video on social media that showcased the moment Kate descended Mount Snowdon hand-in-hand with her brother, James. Phillip Tebajjwa, the hiker in question, expressed his surprise and excitement at interacting with royalty while celebrating the achievement of their climb. He later recounted: “There I was, congratulating fellow climbers as they made their way down from the windy summit… little did I know I was actually speaking to royalty.”
The Royal Marsden Cancer Charity is particularly significant to Princess Kate, as it is affiliated with the renowned hospital where she received treatment during her battle with cancer. Her motivation for the challenge is deeply rooted in her wish to highlight the importance of support and community during difficult times. Prince William and their three children—Prince George, Princess Charlotte, and Prince Louis—along with Kate’s parents, Carole and Michael Middleton, were present to celebrate her achievement at the base of Snowdon.
James Middleton, who has been a vocal supporter of his sister throughout her journey, expressed his pride in Kate’s accomplishments on social media, commenting on her Instagram post with heartfelt emojis that conveyed his affection and admiration. The sibling bond was beautifully illustrated during their hike, with James’s dog accompanying them for part of the challenge.
In March 2024, Kate had publicly shared that she was undergoing treatment for an undisclosed form of cancer, with James expressing his unwavering support through social media. He used a hiking metaphor to reflect on their strong family ties, writing: “Over the years, we have climbed many mountains together. As a family, we will climb this one with you too.” This sentiment underpins the familial support that is vital during such trying periods of life.
James opened up about the importance of family, stating, “We are a close family. It is always important to have support around you and not do things alone.” He emphasized that many people experience challenges in life, regardless of their background, and that sharing these struggles can foster a sense of community and connection.
Following her successful climb and announcement regarding her new role as joint patron of The Royal Marsden NHS Foundation Trust, the Royal Marsden Cancer Charity initiated a fundraising campaign in Princess Kate’s honour. The aim of this campaign is to enhance holistic care for cancer patients, complementing the charity’s ongoing commitment to supporting individuals facing cancer.
Since revealing her diagnosis, Kate has reduced her public engagement to focus on her health but expressed relief when announcing her remission in January 2025. Her emotional visit to the Royal Marsden Hospital showcased her commitment to the cause and her gratitude for the care she received.
The Princess of Wales’s journey not only highlights her resilience but also serves as a reminder of the ongoing need for support within families and communities, particularly for those navigating health challenges. As she continues to advocate for cancer awareness, her determination and familial support resonate powerfully, inspiring others to confront their own struggles with courage and solidarity.
