For those of you who don't already know, I'm going to be walking up Ben Nevis, Scaffell Pike and Snowdon in 24 hours! It's around 23 miles in total which is obviously less than a marathon, but it's the stopping and starting, the upping and downing and sleeping in a car that will make it tough.

I'm trying to raise money for Crisis (and selfishly shed some pre-wedding pounds too) so if you have any cash to spare I'd really appreciate your sponsorship. I've paid £100 myself, and need to raise at least £150 for the team, so please contribute what you can.

If you're worried about using this site here's a bit on why you needn't worry:

Donating through JustGiving is simple, fast and totally secure. Your details are safe with JustGiving – they’ll never sell them on or send unwanted emails. Once you donate, they’ll send your money directly to the charity and make sure Gift Aid is reclaimed on every eligible donation by a UK taxpayer. So it’s the most efficient way to donate - I raise more, whilst saving time and cutting costs for the charity.

So please dig deep and donate now.
