In about five hours, Ranulph Fiennes sets off for his latest challenge, to climb the treacherous 'death wall', the North Face of the Eiger. Good luck, Ran – I'll have a gargantuan Easter egg waiting for you when you get back.
Do please support this amazing man in this deadly challenge – he's aiming to raise £1.5m for charity, so do follow the links to find out more.
Keep your fingers crossed for him, will him up that cliff, and back home to his family, in one piece and as soon as possible.
