I managed to scale Mow Cop today for the first time on a road bike. To be honest the Mount Pleasant route is slightly easier than all the way from the bottom of Station Bank.
My previous two attempts have seen me turning off at the Mount Pleasant road first attempt and then getting off and walking from the Cheshire View pub second attempt, right at the bottom of the 23% section.
You know a hill's hard when you have a dog walker giving you words of encouragement near the top and then cyclists coming the other way congratulating you when you're at the top.
Not sure where Alsagers Bank is. I can guess it's near Alsager though
I'll give that a go next (once I find it) and see how it compares.
