It came up in conversation the other day and remained unresolved with google also failing turn up a good answer...
so out of interest, anybody knows who the current holder of the Pennine Way ladies record is?

Best time I could come up with was the Spine Race record which is held by Debbie Brupbacher in a time of 153h 17m (6d9h17m), but I would have thought that at some point some fast lady would have done it in summer, producing a presumably faster time?
