Have you ever stood on a 10m diving board and peered down? It's a long way. Rhiannan Iffland, world champion cliff diver, leaps off at least double that! That's taller than a telephone pole and as big as a Brachiosaurus. But it's not easy. She had to conquer her fears to become the best.

Written and narrated by 10-year-old Evie Bond.
