The difference your fundraising makes
Nearly 1 in 2 of us will get cancer in our lifetime*, but your fundraising can make a difference.
By taking on the Run 100 Miles Challenge, you're supporting the research that helps beat it.
£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.
