Already have your own place?
If you’ve secured your own place in a run, walk or cycling event, you can still choose to support Rainbows. There’s no need to book through us – simply let our team know that you’ll be fundraising for Rainbows and we’ll help you get started.
We’ll be with you along the way
Taking on a challenge is a big commitment, but you won’t be doing it alone. From the moment you sign up, our Fundraising Team will be there to help you make the most of your experience.
We can support you with fundraising advice and materials, help you share your challenge and give you plenty of encouragement as the big day approaches.
