Aren't pedestrians supposed to keep right on roads with no pavement in the UK?
I tend to be fairly relaxed about this sort of thing. I'm on a cycleway because I don't want to mess with traffic, and that means I have to accept pedestrians will be on the same bit of tarmac and have every right to be there. I'm the most dangerous thing on the cycleway and it's my job to work around them, not the other way around.
Part of the point of cycling as opposed to driving for me is that I'm not assuming I have the right of way.
