I think it was Nam who had Gordon Ramsey throw up on her bag. She was most put out becasue the bag contained the special needs items of her runners and she didn't see why he should spoil everyone elses chances of doing well.
Mudchute was a godsend when I did FLM in 2009. You come around the Isle of Dogs with very little support and you are also very much aware that you are geographically running away from the finish line at that point. Then, just as you get back into a populated part of the course there is a huge crowd of wonderful people offering hugs, jelly babies and anything else you want or need. It took the pain out of the next 5 miles for me.
I've never officially put my name down as a supporter in the past but I have turned up on the day and helped out two or three times. We can never have enough hands so while it would make organisation easier if you could commit in advance, please feel free to turn up on the day if you suddenly find yourself free.
