This is the official Cragg Vale hill climb route. There is a very gentle slope up to the start of this from the sign in Mytholmroyd but I time myself on this section. It is 7.7 km in length with an average gradient of 3.8%. There is a steeper section at 8-9% for a few hundred metres mid-climb but overall this is a fairly gentle climb. The main difficulty is that the second half is over exposed moorland and there is usually a cross-headwind up there which can sometimes be tougher than the climb itself!
