Looking for a charity place?

We have places in some of the UK's top challenge events. Our registration fees are often much lower than it would cost to register independently, and places are guaranteed! In return, we ask for a minimum sponsorship fee, and we'll support you to reach these goals!

If you have a fundraising idea you'd like to discuss, we'd love to chat. Please contact our fundraising team at [email protected]
