Had a mail today saying event postposed for a week due to the weather, not in respect of the run (he'd run that in anything) but car park issues and non gritting etc. And it's a heaving great hill to get up in the car from either direction.
Obviously check for yourselves etc.
Re cost, no it's not a cheapie by any means, but it is a bit different from your run of the mill 10K around an industrial estate. I regularly run the courses in training but the race is always a bit more special.
