We’re the UK’s leading charity for Crohn’s and Colitis.

Thank you for wanting to support us in the TCS London Marathon. By doing so you are helping improve the lives of those affected by Crohn's and Colitis.

Right now, over 500,000 people in the UK are living with a lifelong disease that many people have never heard of.

We’re working to improve diagnosis and treatment; to fund research and to raise awareness.
