I can see the mileage being about right as you can follow the Pennine Way over Blackhill to Crowden and over Bleaklow adding more uneccessary distance on and if you were to follow PW all the way to Snake:eek:
But I must admit the ascent is a bit of a surprise but having worked it out roughly on an old fashion paper map I reckoned about 4,300ft so not far out.
