In a post shared on Instagram on June 28, Kate revealed she completed the National Three Peaks — Ben Nevis, Scafell Pike and Snowdon — within 24 hours, including a summit photo on Ben Nevis on June 27. She finished on Snowdon and was met by Prince William, their three children and members of her family.
Kate described the effort as a way to "explore life beyond diagnosis" and to raise funds for the Royal Marsden Cancer Charity. She urged a whole‑person approach to care, noting holistic therapies can support wellbeing alongside clinical treatment and that the goal is to make supportive care a routine part of cancer services.
