In reply to andy guppy:
Nice site - the cobbled climbs round there are brilliant; I've ridden quite a few of them now. Trooper Lane and Old Lane both look brutally hard (in different ways). The toughest I've found so far was Gibb Lane - like Thwaites with the Shibden Wall stuck on top of it with massive gaps to avoid; absolutely desperate!
Some steep tarmac to be found too - look for a little road called Rosemary Lane - kicks up viciously at the bottom (think Hardknott steepness) then a remorseless slog to the top. If you approach it from Bottoms (fnar) you get another section of savage cobbles to soften you up first.
Superb riding round there - never seems busy either.
