top bit was always very slippery ruts, interesting but never going to be left that way in the long run as it allows too much water erosion.
Rode the path to the right of that one from the Man Nick gate, goes up the shoulder of Mam Tor and down to Hollins X. That has been smoothed off, filling in the small ruts, and seemed to have been done quite considerately as it was still generally narrowish and stayed on the line of the existing path rather than straight lining the small corners.
The track from Hollins X down to Greenlands Farm (rock steps at the top) is getting rally bad though, ruts really starting to deepen on the lower section. Makes for a great DH though
