Walk, jog, or run to raise money for sickle cell!

We rely on your kind fundraising to keep doing the work we do. Every fundraiser allows us to reach more people, run more activities, and improve the lives of those living with sickle cell.

The Sickle Cell Society is the only national charity in the UK that supports and represents people affected by a sickle cell disorder to improve their overall quality of life. First set up as a registered charity in 1979, the Sickle Cell Society has been working alongside health care professionals, parents, and people living with sickle cell to raise awareness of the disorder. The Society’s aim is to support those living with sickle cell, empowering them to achieve their full potential.

Thank you for your support. If you have any questions, then please don’t hesitate to get in touch: fundraising@sicklecellsociety.org
