In reply to tony:
Up to Burley Woodhead, turn Southish and go past Weecher reservoir, over Baildon Moor, then back round past Harvey Smith's gaff and over Bingley Moor on to Rombalds Moor, along to White Crag at the Addingham Moorside end, drop down to Panorama reservoir, back around the edge of the moor ? Probably nearer to 11-12 miles ?
