In short: Far, far, too many people for the course. Badly organised. In full: This was my fourth time doing this race. It is around double the size of when I first ran it. The course and the organisation simply can not cope with this number of runners.
I don't have any detail to add to the many comments here a. I enjoyed the race despite the flaws and the weather. I'll probably do it again next year. However, unless some lessons have been learned I won't be doing it again after that. Date of review: February 23, 2010
