A few thoughts:
The description of your Ditchling Beacon ride suggests to me you had been trying just a bit too hard up until that point, or that you hadn't been keeping up with eating, or both.
I think you have a point. I usually manage my rides with just a small snack halfway. Also, on my diet I am generally pretty low carb and I find that works well for me from a weight loss point of view. I think for these longer rides with hills I need to carb load the night before and in the morning. One of the guys who rode up the Beacon said they had eaten a high glucose bar about 10 minutes before. The problem was not my heart or breathing, it was my legs. They totally cramped up solid when faced with any intense pressure on the pedals, although they were fine on the flat.
I'm 67 and 75 kg. My FTP is 200, and according to intervals.icu that puts me somewhere around the 20th or 30th centile for age 60+. I ride with a group once a week, mostly around the same age, and I'm one of the slowest going up the hills. When I think back to my 30s, I was once of the slowest up the hills then as well.
Well done for your perseverence! I rode everywhere on a bicycle between the ages of 10 and 18 - practically nailed to it. However, I then got a motorcycle, then 10 years later a car, and did not buy a bike again until the age of 57 and then didn't ride it regularly until I was 59 - during lockdown. I need to find some regular bike buddies. I tried a local club, but they were all far too hardcore.
The various formulas for max heart rate give you a vague idea of averages for your age, but as an estimate for your personal max HR, they are virtually useless. If you want to monitor your rides using HR, you need to do a maximum or threshold heart rate test.
I am not that fussed about max heart rate, now I have a power meter. I sort of know now what my heart rate is telling me. I try and ride holding the rate between 120 and 130 for as long as possible, although it usually drifts up gradually over the ride to 140ish.
When I started I did not have either a heart rate monitor or power meter. I would go out and do 60-90 minutes flat out, which would finish me off and I would have to go and lie down for the rest of the day! So I bought a heart monitor and found that my average rate on those rides was 155 with peaks over 170. Reading round the subject I realised that if I wanted to get fitter I needed to go slower for longer.
I've recently returned to regular cycling after a fair break, and have read a lot about how best to get fit again. I'm not a coach or physiologist. The advice (including from Pogacar's coach) seems to be to spend most of your time at low intensity, doing long rides in zone 2, building up aerobic endurance. This is a slow process, it can take months or years. Once or twice a week, some short, high intensity rides help build up your higher zone power.
I have read that in various places too. I have the time to do 3+ hour rides at the weekend, but I don't feel once a week is enough to build up that endurance.
I am never going to be a racer, and I enjoy long days in the saddle, so that is where I want to get to - as long as I can do the hills as well as the flat bits! I have done an Audax ride of 107km with 836m of hills. It took me 5 hours 28 mins and my average heart rate was 149bpm, rarely below 140 and hitting over 170 on a few occasions - again cramping up at the end (but luckily no Ditchling Beacon). Amazed I survived!
I think I am a bit fitter now. The London to Brighton was 92km with 1,147km of hills. It took me 5 hours 10 minutes. I was a bit slower (of course that included some at walking pace), but my average heart rate was 141.
