Hi Mark, those moorland areas are certainly a bit challenging, I rode all of them bar a 15km loop near Holme Moss, as I did that as a walk with girlfriend. But then I really like really technical XC riding.
The glacial pace I mentioned above was getting a tile which I think is just above your top tiles on Strines. There's no path of any kind going there. I abandoned bike and traipsed cross country for a last few hundred metres to get that tile. Also if you have an accident there, you'll never be found unless you have a PLB to call for help. It may still be within the Sheffield City boundary, but no phone reception at all. Though if the vulture returns, he may find you.
He nested just South East of that tile.
A lot of the N+W corner just outside of your square is particularly hard work. It's a lot of XC trials riding with occasional mountaineering. But it's really beautiful.
Which climbs are the ones you will never repeat?
The only place I've been to and thought, I'm definitely never coming back here again other than busy main roads was when tiling SW Doncaster. Ironically I did exactly that because half way around I realised my GPS had borked so I had to loop back and do that awful section again. Then to add injury to insult, I then got bitten by a dog when cutting back to repeat route. The only other unpleasant ride was the opposite side of Doncaster where I was chased by horrible nasty flies on one gruelling section where I couldn't pedal fast enough through the sandy trail to escape the bitey little buggers. Donny sucks!
