Join #TeamCCLG for the 2025 TCS London Marathon and support children and young people affected by cancer.

We are CCLG: The Children & Young People’s Cancer Association, a charity dedicated to creating a brighter future for children and young people with cancer. Powered by expertise, we unite the children and young people’s cancer community, driving collective action and progress.

We fund and lead pioneering research, provide trusted information and guidance for children and young people with cancer and their families, and bring together professionals to improve treatment, care, and outcomes.

Our work is only possible thanks to the generosity of fundraisers, donors, and supporters who share our mission. Every pound raised helps fund our research, provide trusted information for families, and brings together experts to improve treatment, care and outcomes. Together, we can achieve more.
