I didn't think Gordale Scar was actually on the Way ?
Also, how much actual rock climbing is involved in getting to the top of Pen-y-Ghent ?
It is just a series of rock steps that requires some hands on for balance. The first set are Limestone and quite well polished but with enough choice to get around the worse ones.
The second set are Sandstone or Gritstone which offer improved grip, these are bigger steps, steeper and require a bit of a haul up to gain the plateau.
I wouldn't worry about it, this route is the same as the Pen Y Ghent Fell race, which is an annual run.
