When I want a walk round here I generally jump on a bus to Fox House and do the circuit round Higger Tor but occasionally I do the first part of the round walk
From point 1 ( Hunters Bar ) to Ringinglow but then down Ringinglow Rd. back onto Ecclesall Rd. and your starting point. It's all steady going with mild uphill parts , little bit muddy but lots of woods and water.
2 hours at an easy pace?
You even get to see an Alpaca farm in Ringinglow!
Only downside is Ringinglow Rd. is just that. A road.
Thats the boring bit but thats what you get for walks near the city I guess.
