78% of current FTP but this was 4 years ago and it was about 82% then.
I think I could beat it quite easily now if I had the motivation.

If you can hold close to FTP for 2 hours then your FTP must be a lot higher than you thought at the time.
Not according to a ~60 minute all-out effort.

FTP 260 hold but generally don’t do 2 hour rides but my SS is about a 2 hour loop and end up doing close to 230 average. My regular is holding just above 200 (76%) for 3.5-4 hours.

i mean 3% is a lot tbh
sure, but i was more surprised at how long my 2h was, compared to my 3h 
Anyway, 1% at my level is not many watts still 
I am similar to this so am assuming my ftp measurement is wrong.
Current FTP 267
Recent London triathlon bike leg (2hr 15m c.80k) NP267 with IF1.0 and VI 1.05
So need to re test I think.
Updating this, based on my last two 50miles TT (1w between them but 76s bl00dy headwinds) and my AIFTP my 2 hour power is 78% of my AIFTP.

Right about 90% according the the AI FTP, which was really close to my estimate of FTP as well. This was a 2 hour sweetspot effort on the trainer, so a very steady effort.

Last 6 weeks:
FTP 303
2HP 213 - 70%
All time best (2019)
FTP 330
2HP 234 - 71%
Caveat is I don’t recall ever putting in a full effort for 2 hours, even when on much longer rides, as I mostly aim to be conservative on longer rides.
