Think there are a fair few riders that need to think more about the results of their actions. The amount of times I’ve seen cyclists riding like knobs among livestock and people is a order of magnitude more than horse riders acting the same. Yes there are a lot more cyclists than horse riders, but still there are a lot of unthinking people out there that if they did some simple things that would make life a lot easier allround.
Don’t slam on your brakes at the last moment skidding and/or squealing away even thou you have had plenty of time to brake beforehand.
Talk to the rider and the horse it doesn’t matter if the rider has seen/heard you and acknowledged you, has the horse done the same? As far as the horse is concerned you are an an unusual speeding object as you are not person shaped and you are moving at a speed thats associated with being a predator and not a people shaped object who can be trusted.
It doesn’t talk much brain power to see by their body language if they are aware of you and are relaxed about you being near them look at their ears.
Imagine you are a person on their scale how much personal space would you need? Think about all the times someone has got inside your zone and how uneasy you feel about it.
As for the crap debate they were stepping through our crap (as were we) until 100 odd years ago so don’t get too hett up about it. It’s easy enough to clean off, lots easier than sheep crap and you are not likely to catch too much off it unlike dog eggs.
We are all on a crowded island, learn to get on life is so much easier if you do.
