Can't help but agree with other comments here. Had this been billed - and priced! - as a fat-ass/no-frills event, no cause for complaint. It wasn't. Looking at what you get in other similarly priced events, it is very poor value for money, which is a shame, as the course and surroundings are (or would be in better weather) spectacular. Very very disappointing, it really should be one of the 'must-do' events of the marathon calendar, but I can't see that happening unless the present organisers have a re-think of how it is managed.
On the vest front, I think the reason later finishers ended up with the wrong size could again be put down to poor organisation. I have a medium, which is far too big for me, not that I would ever wear it anyway. There was no obvious sorting of the bags into sizes, or none that my near-hypothermic brain could fathom. Why didn't the people manning the 'goody bag' stand ask what size you wanted? Also, the energy bars would have been appreciated on the course, rather than just at the end - I think this is the first marathon I have ever seen where no additional sustenance beyond water and the odd gel was provided. Great Yarmouth was equally wet, but they still managed to provide jelly babies etc. Coffee and tea at the end would have been fantastic too.
I am curious, too, about how much Anglian Water made out of this and will certainly email them to try and find out.
To finish on a positive note, the youngsters marshalling were exceptional. Cheerful and smiling despite the weather conditions, even at the end. I hope a generous donation is made to them.
