Would certainly bugger up a few PB's if we had to stop for two minutes at 11. 
Same weekend as the Slog as well....... completely different type of race and totally different part of the country but still strongly supported by Forum runners.
The organisers bless their cotton sock are never going to please everyone, lets be honest. What we need now is a sensible well thought out decision as to what they are going to do about next years race. This one is lost and gone, the money has been spent on all the infrastructure that goes with the race and I for one am not expecting or asking for it back. I would imagine they have taken a look at this years race calender and found a Marathon less weekend in the South/South East of England and slotted a potential date in there. It clashes with Rememberance Sunday which rules it out for me but maybe they have not realised this.
Luton in December was or always used to be traditionally the last marathon of the year, We have had one cancellation due to the weather in 11 years, (last one was the police stopping the running because of the accident remember). I have done the thing in sleet, rain and howling gales without too much moaning but the ice would have made it treacherous (sp) this year.
Leave it where it traditionally is and put a disclaimer and a bloody big reminder on the entry form that it is a possibiluty it will suffer due to the weather and that people are not likely to get their money back. Entering a December marathon is a risk we all take.
