Join us on this special one-day challenge and tackle a breath-taking coastal section of the South Downs National Trail whilst raising vital funds for The Royal Marsden Cancer Charity.
At 26 miles in a single day, the South Downs Challenge is not for the faint of heart, but the breath-taking views and the sense of achievement at the finish line will be unrivalled!
Join Team Marsden for an unforgettable trek organised especially for The Royal Marsden Cancer Charity by our amazing partners at Charity Challenge!
Whether you sign up by yourself or with a group, you will be trekking alongside fellow supporters of The Royal Marsden Cancer Charity. Registration is £50 per person. There are then two fundraising options you can choose from a minimum sponsorship option or you can choose to self fund your challenge.
If you choose the minimum sponsorship option, you pledge to raise £235 for The Royal Marsden Cancer Charity and the charity will pay your challenge costs. If you choose the self funder option, you will pay the event organisers, Charity Challenge the challenge costs of £115 nine weeks before the event. When you self-fund there is no minimum target but we hope you will try and raise as much as you can for the amazing work of The Royal Marsden.
You will have a dedicated member of The Royal Marsden Cancer Charity team on hand to help you with advice and tips on fundraising. We will be there for you every step of the way!
Our partners at Charity Challenge will provide everything you need to help get you trek ready including training plans and discounts for any new gear you might need to purchase.

Gemma chose to take on the South Downs Trek to thank The Royal Marsden for the care her mum received after a throat cancer diagnosis.
“I signed up while my mum was going through treatment. The team there couldn't have been a better support for her, every step of the way, so I wanted to find a challenge to hopefully help me raise some money as a thank you for that support.
"I raised more than I thought I could, and the South Downs Challenge itself was an amazing achievement for myself. It was extremely well organised; the staff were so encouraging and highly experienced. They kept us fed, watered and smiling throughout. The scenery was stunning!”
Thanks to supporters like Gemma, we continue to fund vital research and care for all those affected by cancer.
