When you sign up, we'll create your online Giving Page

There's no set fundraising target

You set your own goals. But we do recommend you set yourself a target of £150. Fundraisers who do set a target raise significantly more.

What your fundraising can do

Whether you surpass your goals or don't quite reach them, the money you raise will help fund life-saving cancer research.

£70

could fund a clinical research grant for one day, funding doctors and nurses to find new ways to beat cancer.

£130

could fund a cancer nurse for one day, giving people confidential cancer support and guidance.

£170

could fund a trial for one day to test new radiotherapy techniques for treating bile duct cancer.
