Jogging is awful

I am a ‘walk lots, hate running’ person. I think partly it’s the intensity of the exercise, making my chest hurt and partly that it uses muscles in a different way so legs which feel strong when you’re walking suddenly feel weak. I quite liked running junior parkrun with my 6 year old as that meant I could run really slowly without feeling stupid or getting bored. And over the summer we played football together sometimes, running around and trying to tackle each other, which was fun! I’m trying to strengthen my running muscles a bit by doing very short runs when I walk. My ambition is just to be able to run back to the house when we realise something vital has been forgotten for school without feeling like a wreck. Beyond that I have no desire to ‘go for a run’, I’ll get my exercise other ways.

Might check the Maffletone method. Which is extremely slow running.
Basically, you need to do it to get used to it.

you must jog slow enough to be able to carry on a conversation.
This baffles me because that speed for me is walking, anything faster and I'm breathless.

Stretch before you start
Warm up with a fast walk
Slowly turn it into a jog
At first, when you jog, make sure your whole foot doesn't leave the ground - so concentrate on putting your heel on ground, gradually moving forward till your toes touch ground, move back onto your heel and repeat. This way, you are not putting a lot of impact on your legs.
Actively pant through your mouth. It helps to do this quite dramatically at first. Eventually, you pant less. But the painting helps to get a lot of oxygen into your lungs thereby making you feel less tired.
And as a PP said, you must jog slow enough to be able to carry on a conversation.

You need to embrace the Jeff Galloway method of running... which is walk run walk.
I completed a marathon in just twenty minutes more than my regular runner DH following the Jeff-ing method

If you really hate it but enjoy other forms of effective cardio exercise, do those instead.

That's what happens when you first run but each time you can run that bit further .
Even the most athletic have to train nobody can just run a marathon without training.
I've been running years but I'm still rubbish but I love being out pushing myself that bit further and the feeling at the end .
It's not for everyone but don't think its easy for everyone it's not .

Go slower? You should be going slow enough to carry on a conversation.
Why do you need to keep stopping - do your legs hurt, is it your breathing, or something else? Next time you try c25k, once you can finish the runs in week 1, move to week 2. If you need to repeat week 1, that's fine. Some people repeat each week.

It feels wrong to me. I’m better doing a Joe Wicks 20 min workout and some walking.

Yes it will get easier but you may not ever actually enjoy it, I didn't!
There are other forms of exercise that are more effective and fun.

It's BALLS op I hate it too. I can do HITT till the cows come home, cross training hard for ages...no problem....but fuck jogging. The moment I get out something starts to hurt, hip or ankle or stitich, or my eyes water for no reason or I inhale a fly...last week I got chased by a flock or really pissed off seagulls. And it's so boring just plod plod plod. It's rubbish
