With a flight of locks as close as these, Clare would normally have walked ahead to each one. However immediately after the top lock there is a short (100 yards) tunnel. We walked through the tunnel yesterday and found that though there is a towpath, it is narrow and poorly lit. I offered Clare the option of riding through, which she accepted. Unfortunately this also required her to cross the wooden railing that separates the path from the canal. She managed, but complained that she had twisted something. Getting off at the far end was slightly easier.
