Davina's Sport Relief challenge
She's cycled hundreds of miles in the driving rain, climbed England's highest mountain while knee-deep in snow, and this morning she's set to swim a mile in near freezing water.
But unfortunately Davina McCall isn't even half way through her challenge yet. The TV presenter set off from Edinburgh on Saturday with the aim of cycling, walking and running 500 miles to London in aid of Sport Relief.
She says she's taken up the challenge to raise money to provide support for women and girls in Kenya. She joined us live from the banks of Windemere before she kicked off today's effort.
