alright mate. There is some great riding around here. I’ve not got any maps to help you with but have a look at:
redmires reservoirs, over stanadge pole, either down the bridleway to the left or straight on down long causway.
from there you can either put in a few road miles to shatton moor or head back towards sheffield and do lady cannings plantation \ houndkirk moor towards the fox house pub.
From there you can head towards blackamoor, there are various bridleways well worth an explore.
sorry I can’t give you route maps or anything but all these names are on the 1/50,000 OS so hopefully you can figure it out. the vertebrate graphics book mentioned above is called dark peak mountain biking I think and includes these routes.
