Why when I go out at a fundamental pace (Zone 3) (about 2 hours 30 minutes) the training load shows a decrease?

I think that nobody can really tell without seeing your training load stats, but the apparent answer would be - because your training load is lower than before. I suspect this is not what you want to hear, though.

However, the reported lower training load will not cause the drop of VO₂max. Training load is not being used for the VO₂max calculation. It uses the heart-rate, HRV, respiratory rate, the elevation profile, and the pace. So if your VO₂max dropped, it is most likely because your HR was higher (or HRV lower) for given pace than it was supposed to be.

Perhaps reading the following article may give you some clues:

Hi,

I don't think it's the previous load that is causing this decrease. On the attached graph the last point corresponds to my run today (29km 5'30min/km 02:39:52) and you can see that this specific run brings the load down significantly.

I've already read the article but it doesn't add anything concrete. The only conclusion I can draw is that my body did not need to overcompensate after this outing. Which in itself seems normal since I'm not supposed to push myself at a fundamental pace.

And I come back to my original conclusion, the EPOC fitbeat calculation does not know how to take into account this type of run.

I do not see any graph in your post, but if the Acute Training Load is today lower than yesterday, then it definitely means it was higher yesterday 

Please note that the Acute Training Load is calculated as a weighted sum of the Exercise Load of all workouts for the past 7 days. If it drops, it si not necessarily because of the last workout alone, but because the weighted sum for the last 7 days is lower today, than it was yesterday.

In my opinion, it is necessarily the last training session that brings down the load. I always train on the same days. And last Wednesday it was a split session. It lasted less time but the heart rate went up (logical). On a sliding week, that's the only difference. The EPOC Fitbeat calculation "prefers" that the heart rate goes up, to give a workload.

In my opinion and if I take into account that the fundamental pace sessions are important, the training load calculation is not correct.

OK, the graph is now included in your post, but you did not show the Exercise Load, so it is still difficult to guess. When you go to the Training Status report, it shows the Exercise Load graph just above the Acute Training Load. Please post both of them

Hi,

I'm not sure I understand the requested graphic. Is it the same with the value? Like below?

No, I mean these ones from https://connect.garmin.com/modern/report/-1/running/last_four_weeks :
