I’ll answer for Harry as we were riding together.
We ended up doing the 4 passes going up from honister slate quarry, over and down warnscale, scarth gap, up and over to black sail hostel, up over black sail pass, up great gable then sty head to stockley bridge, then back to seatoller and back up to the quarry where we parked.
There was a LOT of hiking up hill, some good descents, by the end of it I was knackered, and we just caught the last half hour of daylight by the time the bikes were packed up. The weather held off which was a bonus, only one flat and luckily this time Harry brought a spare rear mech!
