Join Team Marsden and help change how cancer is treated forever.

We are proud to be the charity partner of the year for the Hampton Court Palace Half Marathon in 2027. Join The Royal Marsden Cancer Charity at the start line, and with your help we can revolutionise cancer treatment, and deliver world-leading care.

The Royal Marsden Cancer Charity raises money for The Royal Marsden to help save the lives of people affected by cancer, everywhere. When you run with us, the money you raise could support: 

  • Life-saving research – including clinical trials and the development of new drugs that will transform the lives of cancer patients at The Royal Marsden, across the UK and around the world.
  • World-leading treatment and care – delivering tailored and personalised treatment, which cares for the whole person, not just their illness. 
  • State-of-the-art equipment – from improved cancer imaging to advanced robotic surgery and the latest radiotherapy technology to drive breakthroughs in diagnosis and treatment. 
  • Modern patient environments – allowing the hospital to build new facilities and refurbish existing ones, so that patients are cared for in the most welcoming, dignified and peaceful environments.

Your support will make a huge difference to people like Jenny.

Jenny was just 23 when she was diagnosed with a brain tumour, after she started suffering from seizures whilst backpacking around Southeast Asia.

Following surgery to remove the tumour, she was referred to The Royal Marsden for further treatment and has benefitted from radiotherapy on the Charity-funded Cedar Linac machine.

“I’m so glad to have had access to the Cedar Linac machine and knowing now that it’s been funded by supporters of The Royal Marsden Cancer Charity makes me feel very grateful to everyone who has donated.”

Two years later, following surgery, radiotherapy and chemotherapy, Jenny has finished her treatment, and her scans continue to be clear. She took on the Hampton Court Palace Half Marathon in 2025 as a way of saying thank you for the care she received.

“Crossing that finish line felt incredible—not just because I completed the race, but because I was supporting such an amazing charity in the process.”

“It feels like being part of a wonderful, supportive community, and I’m so deeply grateful. You’re making an extraordinary difference, and I hope you know how much it means.”

Sign up now to take on the Palace Half Marathon for The Royal Marsden Cancer Charity or use your own place to run with us and you’ll be helping make a difference to the lives of cancer patients like Jenny, everywhere.
