'A new heart would mean the world to me'
Anna Hadley has a rare condition which affects the heart's ability to pump blood.
The 14-year-old, from Worcester, was diagnosed with restrictive cardiomyopathy last year.
She is on the waiting list for a new heart, as are 41 other children in the UK, according to the NHS Blood and Transplant service.
Anna is doing a sponsored 212km (132-mile) bike ride with her father to raise awareness of the need for child donors.
