This sounds interesting. Its just up the road from me and I've never run this before. Late August I believe. I'll keep it on my radar TF, as I'm training and building my legs up for doing my 1st ever marathon in the 1st half of next year.
That was an interesting read. Didn't experience any marshalling issues myself, but then I was about 3/4's of the way down the field, so any slip ups would have been corrected by the time I came past (you hope).
