I agree with you OP!!
And I am not a dog walker.
There's too much competition for park space now, it's getting ridiculous. The basic walker with no dogs is the one excluded.
Firstly, (and as dog owner you probably won't appreciate this part) there's been a massive increase in dog ownership, that's enough already, but also there's the increase in the amount of professional dog walkers with several dogs at once taking up paths. There's also now I noticed, professional dog walker meetups where you are confronted with two or more people walking anything from 6 or more dogs between them. Of course YOU are the one expected to move. The dog mess issue is another thread.
Then the personal trainers and the outside gyms. Ok one-on-one fine maybe. But now you get exercise groups in the park, one I saw recently had about 30 people! and a van with equipment dumbells, skipping ropes etc strewn on the grass and taking up the narrow road into the car park. These groups also jog. So well after Park Run you find yourself with more jogger groups. In fact all weekend and evenings.
Then there's the newest social annoyance of people bringing their families and using hammocks and tents, mini-camping, cooking and screening off an entire area - for themselves.
Then the concerts which bang on for 3 days straight that the council assures us brings in revenue (which strangely the local shops, cafes and bars never see as no one goes out) and which suspiciously seem to require the cutting down of tree branches and leave the park littered with trash.
Add to that the usuals (which are fine but are now vying for space)
The football/rugby/cricket teams
Increased cafe usage - with dogs
Ordinary joggers
Droners
Bird watching groups
Circus
Funfair
Farmers/Craft markets etc etc
With everything going on already and councils saying yes to everyone, who wants to co-opt space being confronted with a P.R can feel like the zenith. There should be a fee at least that can be poured back into the park.
There ought to be designated places for people to run in large groups, but not the parks. Everyone shares the weekend after a 5 day working week, and I don't see why Saturday morning should be exclusively for runners with everything else. My is small so you cannot avoid the paths, so it is virtually exclusive to PR in practice as all of them are taken up with the runners.
If you want to run in the park, run on your own. Take your own timings.
The parks have become like an extension of the city, or a business, when actually, you go to the park because you are trying to escape the city crowd atmosphere.
