Its a level path so that don't hold water.
Well, that's a useful piece of information that you omitted from your original description of the incident - in which you gave the cyclist's age and the name of his dog but left out any detail about what actually happened beyond "as he passed her she slipped". Most pertinently, you haven't answered Lightning Phil's questions, viz:
"Did he ask her to move off the path or is it just something she decided to do? Also close pass at speed or something else?"
It's hard to conclude definitively from what little information you have provided that the cyclist was at fault. Instead it comes across that you are aggrieved at your wife's injury and are responding to this by lashing out at
all cyclists.
I wonder if your wife whilst cycling got run over by a car would elicit the same responses. Oh but that's different aint' it not?
Again, to quote your description of the incident: "as he passed her she slipped"
Yes, that
is very different to being run over by a car.
Shame you you, and be aware karma exists. What goes around comes around.
Wevs.
Hope your wife heals quickly and without too much pain.
