Come to think of it a "pack" of cyclist used to pass me regularly on the way to the pub. About 15 of them all but one was pig ignorant apart from a lady cyclist. All the rest clearly thought it was beneath them to say hello to someone on a touring bike.
This is so typical where I live.
I run as well as cycle, albeit shorter distances and slowly. It’s just my way of engaging with different muscle groups whilst still maintaining a level of basic fitness when I can’t or chose not to cycle. Also I’d rather run in the rain or wet than cycle but that’s just me. I never ride in the dark but will run as long as there’s some street lighting.
Anyway I find that both disciplines have their share of dicks, snobs and those taking themselves uber seriously (whilst taking the opposite stance towards others).
I always offer and return greetings as much as I am able when working hard or basically struggling.
There are lanky gazelle like runners in space age Lycra super hero outfits who ignore anyone like me in shorts and tatty T shirts, there are also cyclists, who also take themselves very seriously, and in their heads have convinced themselves that they are champions in the making, who ignore or turn their noses up at anyone (like me) on a flat bar bike, or any bike that’s not made of
unobtainium, with AI controlled Di gears and costing in excess of £5k for example.
Wherever people are involved you will get a mix of all the human qualities, good and bad, as you would in all and any other situations or circumstances.
