Good ride and endless opportunities to extend it.
If it were me, I’d do the start a little differently and slog up to Heptonstall, do Blue Pig and then take the BW north from Hardcastle Craggs to the House Of Sh*t and then loop over the tops to Walshaw. Then farm track to Widdop.
Then the far end of the ride takes you down Rams Clough. This is great when its dry but in the wet can be a bit of a slog so if its been raining beforehand, carry on down to Hurstwood Res and then you can do a loop of the purpose built swoopy stuff in the woods there.
Rest of the ride is spot on. There are some guides that point you in the direction of a climb up the south side of the valley to Mankinholes once you pop out at Eastwood and then along the London Road back to Hebden. Sack this off unless a) you love big climbs on steep roads, b) you like long slogs along gradually climbing broken farm tracks and c) you know of the good, cheeky descent options back to the station area.
