@raven Did you try it with the same activity type for Warmup? So no Crosstraining - Running, but Running - Running?
I heard this should work. Not happy with it as running activities also creates VO2MAX values.
I more typically do a “walk” startup, then end and switch to “run,” but I’ve done “run” then “run” too and it didn’t make a difference. Admittedly it’s been a bit since I tried “run” then “run” so if an update changed things my info may be out of date but I don’t recall updated talking about improvements to ZoneSense on the Race S.
Now it may be what is being referenced isn’t the ability to get ZoneSense “on” at start of session, but instead, a “run” then “run” might mean you can start the second run at race effort (i.e. no need to restrict yourself to only a warmup) in the first ten minutes, such that you still only see ZoneSense after the 10m mark but the fast start won’t mess up the calibration. That nuance I have not tested and I’d be uncertain how to verify.
Yesterday I did a 2.2km in 18:07 walk with a little “pickups” here and there to make an average 8:08/km pace. ZoneSense measured my aerobic threshold lower than I’d expect, 134bpm compared to my normal 144bpm. Actual HR averaged 123bpm, max HR 146bpm so my pickups did elevate a bit.
When I ended the walk I immediately did a run effort, which was 8m threshold, followed by 8m recovery, then 8m threshold again, for a total 5km in 26:50, average overall pace 5:22/km but “attack” efforts averaged 4:29/km and 4:36/km. Average HR 152bpm, max HR 168bpm. ZoneSense measured aerobic threshold as 160bpm, which is close to what I think of it at 162bpm. It did not make a recommendation for aerobic threshold.
The second session did not “start” showing ZoneSense until after the first ten minutes. I did not rely on using ZoneSense for either session “live” as the first was too low effort to really care, while the second I was more focused on maintaining my attack pace for the work efforts, while the recovery I simply used standard HR and RPE to make sure I was down to zone2 but not allowing myself to get into zone1.
So if the claim is “without that first session, the ZoneSense graph on the second session would be worse,” then perhaps. I’d need a second Suunto device to properly test that, using the first as normal, and the second not recording the walk effort at all and only starting it on the actual run, then compare results. But what I want is a “full” ZoneSense graph starting from session start to session end.
