I ran this last year and had the same experiences as everyone above.
The worst thing about the whole thing is the lack of water on the 10K, (i.e.) none. There was a water station but the kids manning the water station where to more content with throwing the water over each other than giving it out.
There were large numbers of people collasping and at times there were not enough medical people to help.
I will never run this again! Save your money and if you want to run around paddock wood then do the paddock wood half. That is an excellent event.
