Taking on a challenge is not only really satisfying, it’s also a great way to raise funds for us!

If you have already entered a challenge or are planning some sort fund raising event you can raise money for us by uploading the details on our Just Giving Page. This is a great way to support us and it doesn’t matter whether you are planning to hold a zoom quiz or jumping in the sea for a cold water swim with friends. Let us know what you are doing by email and we will do what we can to help by promoting your event on our social media channels.
