@goldbar A horse and rider need 2m space and passing at less than 10mph to mitigate risk to all. That's indisputable. Ignorance is not a defence I'm afraid. Nor is "I had headphones in and was distracted by checking my app for my run time."
Getting bored of posting it, but....
[Riders] should respect your safety, but you [pedestrian] should take care not to obstruct or endanger them. Always remain aware of your [pedestrian] environment and avoid unnecessary distractions.
Why do you think 2m and such a low speed is specified? What might happen when that space/speed is not adhered to?
How about horse people take responsibility for do their best to manage their side of the risk, and people on foot take some responsibility for being aware of the environment they are entering into and take appropriate precautions. Such as not to potentially startle half a tonne of horse that has very likely recently become startled by some other idiot's ignorance?
Otherwise you are quite literally giving the majority of horses a life of misery/death sentence since they are then unable to get the exercise they need and are confined to going round in circles for the rest of their lives.
We then may as well go the whole hog and tarmac over bridleways to avoid trip hazards (we're almost at that stage so that cyclists can use them, making them less suitable for horses) and ban all domesticated species/farm machinery from the countryside where there are footpaths and bridleways, incase there's an accident involving them?
What about making bridleways just for those with bridles and those okay with the risk/willing to respect them (like the majority of users) and footpaths just for people on foot who are not okay with it?
