sychronicity, I was just reading this this morning which is along similar lines. Talk of 'Roman Roads' can be suspect, can't it, because it's one of those things you just accept (history starts with the romans after all). Especially on hill tops where there was nothing much (bar soggy bits) to make you divert, why shouldn't prehistoric tracks have been just as straight, and the obvious route for later users like the Romans?

"The Bull Ring lies practically on a line from Arbor Low to Chinley Churn, which line passes over Churn Hole near Chelmorton, and the ancient road from the south-west close to Arbor Low runs within a few yards of the Bull Ring; this may only be a coincidence, but it is certainly significant and suggests a connection between the two circles.
It has also been suggested by the late Mr, W, J, Andrew and others that a Roman road passed in this direction from Fairfield, which is said to be lost to the north of the great lime ash heap at Lower Bibbington. Careful inquiries as to this however elicit no information. It may be that an old road or track did run in this direction before the present main road was constructed, An old inhabitant used to speak of a Roman road by a now disused track above Alstonlee, but again we have to corroboration, At the same time, although proof is lacking, these old tales should not be altogether disregarded."

No. That function was probably taken by the curricks. There would have been summer herdsmen in the higher pastures during the summer.
