In the meantime I did Z1 ride for 90 mins.
After several weeks of Garmin connect saying I was over reaching on my 'training'. It recommended I needed more low intensity sessions
Now I've just moved into productive training .
Do you pay much attention to this monitoring, whether Garmin, Trainer Road, training Peaks etc ?
I look at it, but I find the Garmin Training Status relies too heavily on VO2max data.
Literally I can set a record-equalling VO2max on a Saturday and it loves it. Then if I do 2 or 3 days of Zone 2 it says I'm unproductive because it erroneously seems to think I can't do that VO2max effort again (even though I haven't tried to).
At one point it annoyed me so much I switched off Training Status. Now I tend to look at it with amusement. It has correctly identified two occasions as "Peaking" where I've gone on to have a very good result that day. It isn't nonsense, but its over-reliance on assuming you will go for a high VO2max effort every few days is frustrating.
Taken alongside HRV and RHR it's another data point though - which is why I now leave it on.
RHR I find excellent. If I'm fully rested I'll be 46. Up to about 52 overnight after a really heavy ride day, but anything over 55 and I'm fighting a bug. Usually the RHR would tell me that a day or two before I feel any symptoms.
HRV is a great indication of "systemic stress" but that can be either physical or mental. I was physically great back in October but my HRV (and RHR) were poor because I was stressed out handling my mum's probate application. Alcohol really messes with that too. More than one glass of wine will reduce my HRV significantly (and increase RHR). Spirits seem to affect me very strongly.
Body battery is quite good, but I have had some good results with a very poor starting score. It does give you an indication of how well you may have recovered from previous efforts though.
