You might as well add in Pecket Well B while you’re at it – that map shows Pecket Well A, which bears right over a bridge after the first section of packhorse slabs. If you ride back up the main road you can do B too – set off as normal but go straight on instead of bearing right. Watch out for the rim dinging/puncture causing drainage channel right at the start, but once you’re over that it’s a nice rocky descent all the way to the bottom.
Also, on your way to the top of Pecket Well from the Haworth side, keep an eye out for a little snicket of a bridleway on the right. Look on the map in satellite view and you can see it just after Crimsworth Lane and before Elmet Farmhouse. It heads down then left with a short sharp climb at the end that takes you back onto the main road – missing out the tarmac and adding in a bit of a fast running slot challenge.
