Training load focus not lacking all "high aerobic" training, but I get low aerobic or anaerobic scores?

I have couple weeks been using Fenix 6s Pro and I don't get any "high aerobic" numbers to the training load focus, regardless of the training I do instead. Instead they are either low aerobic or then if speed up, it gives instantly anaerobic points, even if my heart rate has been much of the training in high aerobic zone.. Any suggestions what could be wrong here?

  • Hi Gilbert Jakub and all others with the same issue,

    in the meantime on my side the issue is solved because of the Firmware upgrade of the Edge1030Plus from version 5.20 to 6.10.

    So it has clearly nothing to do with any strap used. It was a major FW bug in the 5.20 SW of the Edge1030Plus.

    The first ride I did after the upgrade of E1030Plus to 6.10 had Exercise Load of 195. This caused a jump from 0 to 185 on my High Aerobic training Load. The Low Aerobic and Anaerobic remained unchanged, so 10 points of Exercise Load are 'lost in space'.

    1 week earlier, on FW version 5.20, I did almost exactly the same ride (both done indoor so very comparable) which upped Low Aer with 168 points and that was it. High Aer and Anaer remained the same where the start situation before the rides was also the same: 7-Day training load zero before both rides.

    I suspect that maybe the basic FW version used for the 5.20 version was derived from FW versions earlier used for other devices which have had the same issue in the past as I found reported about elsewhere in this forum (mostly under a particular Garmin device like the Forerunner or Edge type).

    Hope that Garmin will test future FW versions for devices much better than this one because now the whole Training Load Focus  during the live period of 5.20, from 23-July until at least 15-Nov, is totally useless.

    Also let's hope they never use the x.20 version again as root version because then it may be that the bug returns.

  • I have exactly the same problem.  I used to have anaerobic,  low and high aerobic load doing a variety of exercise  - wattbike, skipping, weights, gravel & mtb - long and short rides, flat & hilly. Since start of year I only have low aeroibic. Was HRV status introduced on frnix 6 at same time. Something has definitely changed

  • I have the same issue, but has only appeared after a 4 day mountain bike ride (KAW) so my figures are high as it's a tough ride, I only wore my watch and not my HRM so you can eliminate that from the issue, nothing else has changed, I used to have the high aerobic figures before this event. I would like to add my current HRV has become unbalanced and I would expect this to return to normal after another rest day 

  • I’ve got a similar issue. In charts I can see I’m getting high aerobic time in but load focus shows nothing. I’ve also done 1.5 hr ride with it showing as the activity for the day but having no effect on my training load,  as if I didn’t ride. Do I need an update, if so, how?
