James Middleton's Emotional Instagram Post
In his Instagram post, James wrote: “I’m so incredibly proud of my darling sister.” He recalled a promise made two years ago: “Two years ago, I told you we’d climb this mountain together. We talked about climbing mountains while you were in hospital, and about the incredible healing power that nature can have for both the body and the mind.”
He continued: “So it was such an honour to join you for your Three Peaks Challenge for the Royal Marsden Cancer Charity. Seeing how far you’ve come is nothing short of inspiring. Your strength, resilience, and determination, all while being the most amazing mother, wife, daughter, and sister, inspire me and so many others every single day.”
Charity Challenge for Royal Marsden
Catherine and James completed the Three Peaks Challenge to raise funds for the Royal Marsden Cancer Charity, the hospital where Catherine underwent cancer treatment in 2024 after being diagnosed following surgery. The princess has been in remission since early 2025 and has since returned to royal duties, including an overseas trip.
The challenge involved climbing the highest peaks in Scotland, England, and Wales within 24 hours. The exact amount raised has not been disclosed, but the Royal Marsden Cancer Charity benefits from public donations and events like this.
Close Sibling Bond
The post highlighted the close relationship between the siblings. James spoke about how they had discussed climbing mountains while Catherine was in hospital, showing their deep connection. He urged supporters to “keep being exactly who you are” and directed followers to the link in his bio to learn more or donate to the Royal Marsden Cancer Charity.
