@Mattg576 How long? Looks too short as the downhills push ZS low and not enough sustained effort to go higher. On trails I cannot run downhill fast enough for ZS to show actual effort. That’s why I rely on RPE as well.
-
@Brad_Olwin @Mattg576 to extend on that, in the ZoneSense videos it is said that you don’t want to look at the actual curve of ZoneSense but only on the color. So, a downvard curve within green means nothing, it is just green…

@Brad_Olwin I don’t know what you mean by how long or looks too short, the whole run or the small hills ?

@2b2bff I understand the principles of Zonesense but by that logic my work effort got easier while I ran those hills (which it didn’t, it got harder).
I also understand there isn’t a direct correlation between ZS & HR BUT surely as the work effort increases it would push you up further into the anaerobic state - not nose dive back into low aerobic…

@Mattg576 as @Brad_Olwin said, ZoneSense always needs a couple of minutes to catch up. I remember from the videos that there are physiologic factors (30 seconds) and factors of calculation (2 minutes). So, if your intervals are shorter than those two minutes you won’t see any meaninful effects.
Here I had a run with 3 minute intervals and you can see how ZoneSense had a hard time to catch up, but it reached yellow at the end of the interval…

@Mattg576 The small hills, how long was the uphill, it looks to be short only 3 minutes or so?
-
@2b2bff A perfect example! I don’t use live ZS for less than 6 min. I just use RPE. I will look back at my zones out of curiosity.

The uphills are too short, it is simply green because the hard efforts were not long enough. Have you watched the videos or read the material on ZS. Those explain what you see.

@iterum-tenta A great summary! I think to all forum users here…do not equate HR and ZS values or try to force them to fit together. Suunto has extensive information that explains 99% of the issues raised here. It is a substantial time commitment to view all of the videos.

What mystifies me though is that I was already in an anaerobic state & my workload increased (confirmed by RPE - I was hanging out my ar#e) yet ZS suggests the complete opposite for nearly 10 minutes, I’ve experienced the same many times before…
I have read & watched some of the material but granted not all of it, the answer must in the bits I haven’t watched yet.
Thanks for your reply Brad.
