As for the race route, it is very runnable and there is only one changeover which might be dubious (wainstalls) all the rest are in towns or on (or near) good roads which have been usable for over a week now and are well gritted and clear with warmer weather forecast for the end of the week.

I would say hinchcliffe arms,blackshaw head plus all roads leading to the changeovers are bad.in particular first thing sunday morning.
its bad at blackshaw head,wainstalls and cragg vale at the best of times so imagine all the arguments with the locals,bus drivers,police,ambulance ect!

running on the route is easy but i think the reason is about avoiding snarling all the road routes to and from.
I think if you had pranged your car or slipped on many of the steep descents you would have had something to say.
If i remember right the last time it had to be canceled the hosting club nearly went bankrupt due to all the financial outlay.
it would never be the right decision.
