Just to qualify the detail of my occurrence with said earphoned pedestrian & dog. Being 06.30h, it was dark and the path was only vaguely lit by nearby streetlights. The path itself was about 1.5 metres wide with a steep grassy bank on the left and a fence on the right and ped + dog took the entire width of the path up. Thus I had nowhere to 'go'. I was pretty much trackstanding when I had to call out to bring his attention to my presence. He hadn't noticed my nice shiny headlight, so suggestions as to an appropriate course of action apart from getting off the bike and saying 'S'cuse me please, may I walk past - ?' in a loud enough voice to be heard.
