The 40 Miles in 40 Days Challenge invites you to move at your own pace while making a real difference. Whether you’re walking the dog, running with friends, or fitting in miles around family life, every step counts.

This special anniversary challenge is designed to fit around you - no pressure, no competition, just purpose.

For 40 years, Rainbow Trust has been there for families when they need support most. By taking part, you’ll help us continue providing expert emotional and practical care to families with a seriously ill child.
