Thursday morning got off to a damp start as we left Dudley and headed off up The Birmingham Main Line towards Aldersley junction  through Wolverhampton but with the small obstacle of a run of twenty one narrow locks all downhill which always seem to take longer so we have achieved our target after around seven hours of hard work more  for Hilary than me , at an average speed of one mile per hour and a drop in height of 132 ft in that distance .
