Challenge Yourself to an epic 42km journey through London, following the Thames Path from Hampton Court and trekking a marathon distance to Millenium Bridge!

This is a tough 1 day challenge that will see you walking a marathon-distance from Hampton Court to Millennium Bridge. See the changing landscape from leafy areas of west London through to the bustling city sights further in the east!
Registration is £45 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 £260 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 £125 five 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.
For full details of prices, check out the Thames Footpath Challenge webpage which explains each option available to you for this challenge.
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!
