Problem with that loop, is that the track is closed at Riding Reservoir. Think that's what it is called anyway….. the one above Yateholme reservoir.
Like, proper closed. Fenced off.
There is a nice and cheeky detour, but that needs to be ridden in the other direction.
Best descent in the area is the bw that drops into Marsden from the A640. Almost West to East.
The Wessenden descent is vastly over-rated. I'd use that to get back towards Holmfirth. ie. as a climb.
Would have offered to show you around but I'm away this weekend.
