I did a very similar route 10 days ago from home, I live 2 mls from the North end of Cut Gate. The better way of getting from Dunford to Royston Vasey (Padfield) is to follow the Northern Horse Route instead of dropping down to the West end of the Woodhead tunnel, it’s much more interesting than the old railway line. Also the Cut Gate track will be very wet after a week of continuous rain, when we came down it was dry and dusty but that will not be the case now. Also the bridleway across Thurlstone Moor is a bit dodgy, there is a 100m section just before you drop onto the TPT which is a footpath, the house owner at the end is very aggressive and knows the situation, you may be ok on a weekday but whoever published the route is obviously unaware of the history. Hope this helps, have a good ride.
