I have just been out for a walk, many pedestrians were out and we didn't once have to go within two metres of any of them. Even if they don't change their path, we have time too.
Cyclists and joggers, nearly every one goes by before you have time to move. The cyclists also kept getting caught in ridiculous bottlenecks with each other near paths, at one point three separate households were completely tangled up for quite a while.
I get that you just can't really do your run or cycle if you have to keep stopping every 20 seconds, and round here that's what it would take for them to give people room or time to move. If you live in a quieter area it's fine because you might only encounter one or two others so you probably wouldn't mind slowing to avoid them, and they probably have more room to get out of the way too.
This has been recognised as a problem because on some parts of the London river walk cycling is now banned between 6am and 5 pm. Not sure the message has got out though, and police are having to ask some to dismount and walk by their bike. But that still leaves joggers, have just spoken to an elderly relative who has had a jogger brush right past her huffing and puffing. It's like going out when you have a physical inability to change direction, and come upon people too fast to allow them to.
I am starting to think they need a dedicated space or time for these forms of exercise, or to ban them in busy/urban areas. At the very least they need to say that cycling and running are only permissible in circumstances where they don't mean breaching the two metre rule.
