Our Charity of the Year runners are doing something incredible - running 26.2 miles to help beat childhood cancer.

Join the race to beat childhood cancer
Every week, around five children in the UK lose their lives to cancer. For every child, parent and family - it's time to beat it.
GOSH cares for children with the hardest-to-treat cancers.
But advances have outstripped GOSH's current cancer care facilities, and the hospital needs a new home to help deliver breakthrough therapies.
That home is the Children’s Cancer Centre at GOSH.
Join us and help build it to save more children’s lives.
