Catherine is raising money for Sutton and Chelsea based The Royal Marsden Cancer Charity.
It supported her through her own cancer journey.
The future queen climbed the highest mountains in Scotland, England and Wales, Ben Nevis, Scafell Pike and Snowdon, over the weekend.
She says she took on the trek to “give something back” and raise awareness of the wider impact of serious illness.
Donations to The Royal Marsden Cancer Charity will support the development of a new centre for holistic wellbeing and recovery.
This will show how holistic care can work in practice, which will help enable the creation of a specialist programme for transforming access to holistic care, alongside clinical treatment, for patients across the UK, to enhance physical, psychological and emotional recovery.
Dame Cally Palmer, Chief Executive of The Royal Marsden NHS Foundation Trust, said:
“At The Royal Marsden, we are committed to ensuring every patient has the personalised support they need as they navigate their diagnosis, treatment and life beyond cancer. A patient’s cancer journey doesn’t stop when active treatment stops; it’s important to treat the whole person, not just the illness. Holistic care that complements clinical care plays a vital role in enabling patients to sustain their wellbeing, resilience, and quality of life.
“We are honoured to have Their Royal Highnesses The Prince and Princess of Wales as Joint Patrons of The Royal Marsden. The Princess’s commitment to The Royal Marsden stems from a deep empathy for those facing similar challenges, and we are immensely grateful for this generous support that will make a difference to the lives of so many cancer patients and their families.”
Posting a personal message on Instagram, Her Royal Highness said:
“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.
“We have an opportunity to reshape what the future of holistic cancer care looks like, enabling more people, nationwide, to access the kind of personalised support that can help make a meaningful difference during and after medical treatment.
“This challenge will support The Royal Marsden Cancer Charity, helping to transform access to, and understanding of, holistic care that will enhance recovery and healing for patients across the UK.
“Together, we can stand alongside everyone navigating life with cancer, ensuring no one faces this disease feeling unseen or unsupported.”
