Thanks, Gordo. Looking at this table again, I wonder whether 60-90' for Zone 3 isn't a bit too short of a duration. Wouldn't this mean that a marathon should mostly be in Zone 2? If so, I would find it a bit restrictive, and not aligned with my experience. Perhaps I am missing something, so I please feel free to correct me where I am wrong.

You'll be able to train it up, for sure. I got mine close to 4 hours as an elite. My lactate curve was a "flat profile" - so I had a wide Green Zone and a wide gap between LT1 & LT2.
As for where the marathon falls - for most athletes, looking at velocity, it will be Green Zone
If we look at heart rate then it will appear to be a higher zone.
