I avoid the Bristol-Batch cycle path for my commute during the school holidays. It is chaos, dogs, kids, squirrels!
If everyone showed a bit of common sense for other users (that includes cyclists) then it would be OK.
You get 4 or 5 people walking next to each other and never looking behind to see if anyone is approaching, dogs loose or on extended leads, groups of kids on bikes trying to run everyone off of the track. The ones that get me are the people walking towards you (who can see probably half a mile ahead) who seemingly never notice you coming!
Don’t get me started on the squirrels…!
Do you have an ordinary bell OP?
A lot of people wear headphones and do not hear a bell (in my experience).
