A Positive Legacy for Lucie

"The Half Marathon gave me a special day dedicated to my Nan. Every person who goes out and raises money makes a difference. You’ll never feel bad after you’ve gone out of your comfort zone. It’s the best thing I’ve ever done, so take the leap!"

Brooke, whose nan was patient at Guy's Cancer
