On the evidence of today, find a good bike pack and sub-5 should be easy.

So does that mean you need to get the bike to around 2:30? Achievable on a decent course if you are aero without trashing yourself for the run.
I did 2:40 at IM Barcelona for one of the halves so if I smooth out my power on a fairly flat course even if it’s windy I should be ok.
Something like this minus transitions:
Swim 30min 1900m @1:33/100
Bike 2h40 @210W
Run 1h50
But it’s the training plan I need not the target plan, if you get my meaning.
Cant find anything online apart from a rambling blog with no advice and Taren’s nonsense.

Trainerroad have triathlon plans don’t they? If you like their cycling, as good a place to start as any.
A proper coach is fairly expensive unless you can find someone who is trying to get their coaching badge and wants a guinea pig for a few months.
There’s plenty of sessions posted above that will get you there but it’s more about getting a current baseline and then seeing when you can fit them around your schedule.
Appreciate that’s probably not the answer you were wanting.
As Buzz says though and what about training peaks?
I got to 5:10 self-coached and inconsistent.
It went like this:
Swim 3 times a week - got to 33 mins.
Bike on TrainerRoad and outside every weekend.
Run 3 times a week with a few long ones.
Was fairly to plan but inconsistent as I said.
If you don’t think you can get to sub 1:50 on the run then you know what it takes to get there.
Just swim a bit and batter the bike training. Given 12 months (you said not in 2022) then you should do it fairly easily if you pick a flattish course.
Cotswold, UK Ultimate Half etc.

Yes, and I’ve used all of them I think.
I can use them again as a framework, but they only have RPE targets for swim and run. Years ago I tried converting these into paces but I gave up. I suppose I could do that again, I need to know what paces for;
Swim
50m all-out
100m and 200m hard/9, moderate/6
2000m moderate/6
And so on, for a 30min 1900m outcome.
Same for running. I could take them from something like McMillan running calculator maybe.
Thanks - Can I ask roughly what paces you ran these runs at?
I’ve never gone over 5 hours in a half.
I’d say get your half marathon time standalone under 90 minutes, the bike will slot in around your current swim and that run fitness.
It’s that simple

I ran 1:48 is the race. Thought i was in 1:40 shape but cramped badly and walked a lot (was before I knew my best nutrition strategy)
Most of my longer runs were around 8-8:30/mile.

He’s pretty much said that’s not possible, so smashing the bike up and having a decent ish swim sounds like the only option.

WHY!?!?
What is limiting you running faster than a 1:45?
What is your standalone PB?

You need a 2:30ish bike off a 30min swim and 1:50 run.
Has to be a easier to find 5 mins off the run than the bike if you are at 1:50?
I say all this as if I know what I’m talking about but I’ve never put it into practice.
May target this at UK Ultimate Half next year though.

The moon rising in Capricorn? An old gypsy lady told me on my wedding night? I’m fat and lazy?
Look if I can find a plan I can follow to get me to a 1:50 run split I will revisit that. Until then, it’s just wishful thinking.

You can run under 1:45, simples.
Then it’s 1:40, then 1:35, then 1:30 
That’s 4 x 13 week blocks.
So a year.
First step is a sub-23 parkrun…
You doth think too much.
Step 1: Press the button on your watch (I’ll give up on encouraging using the pace clock)
Step 2: swim 50m all-out
Step 3: stop your watch and look at time.
That’s what pace you can do.
Same for sub-maximal efforts. Chasing time targets is arguably less physiologically accurate than a well judged RPE.
Establish what each pace feels like. Do some training. Notice that the RPE/HR/POWER/SPEED balance all shifts over time.

Found this on a random calculator
75 kg = 1h34 and 70kg = 1h28 if it’s to be believed
I think showing how the same athlete might perform in theory, if you just change the weight
