Brighouse to Queensbury on to Halifax - 21 mile (Brighouse 270)

Route climbing to Queensbury from Brighouse, then dropping down to Halifax, following canal back to Brighouse if open - otherwise road. Canal is open, some detours from main path. Mostly tarmac - 1 short stretch of even cobbles, south of Halifax - normal piece of road.. The first 8 miles or so are mostly uphill - there is also a 1:5 up and down bit. We can take a detour to avoid that section if need be.
