How fantastic would it be to hike up Kilimanjaro?

I was chatting today to former Olympic rowing champ Sarah Winkless, who's off to walk up Mount K in a couple of weeks time, with her brother. She's looking forward to the challenge, but also to the shared moment at the top - a wonderful thing to share with someone you love!

She reckons it costs about £2,500 to make the trek. You start in sweltering temperatures - it is Tanzania, after all. Then, as you go higher, the air gets thinner and it starts to snow! Wow, can you imagine? Not much more expensive than an ordinary holiday abroad, but you'd never forget it, would you? Watch out kids, mum's got a great idea for next year's family holiday. Get the thermals out? Or is it Florida again?
