Be honest. Can you think of anyone less likely to do a 5k obstacle course through mud? I mean, Jesus. When friends at work first suggested I join them to do it, I told them where to stick it. I couldn't think of anything I'd less rather do, even for 'charadee'. But then I got to thinking. When you do something for charity, when you ask friends to part with their cash, you should be doing something different, something that'll be a challenge, something you wouldn't normally do. And god knows, this is so far from something I'd normally do - even though I'm determined to do it in full make up with perfect nails. Though perhaps not in heels. The fact is, many people I love have had cancer, one is in remission at the moment, and some - not least my beloved dad - have died of it. And many of my lovely friends have lost close family and friends to it. So today, on a day when a dear friend who is mourning his mum is very much in my thoughts, I have caved in to the pressure and signed up for this hideous sounding experience. After many months of bad health on my part - including, ironically, a cancer scare - this'll give me something to aim towards so I don't keel over half way round. But I can't emphasise enough I DON'T WANT TO DO THIS so please please make it worth my while by sponsoring me.
