Dark satanic mills, a bit like Huddersfield....only joking (I hail from Calderdale).
Seriously, it is a bit like Huddersfield. Park tarmac paths, on a slight slope, 2 lap circuit.
Terrain also similar to Heaton, Oldham, and others with no trail/mud.
I ran it 2 years ago whilst visiting relatives. I recall there was a sting in the tail in the last 100m as you twist up the hill off the circuit to the finish - assuming its still the same course.
