Delays in speed and pace makes it impossible to follow suggested sprint workout with Fenix 6X Pro Solar version 12.10 RC

I have posted some other threads about the delays in speed and pace on my Fenix 6X Pro Solar (software version is now 12.10 RC).

Today I tried to follow the suggested workout which was a Sprint workout called "3x3x0:[email protected]/h 55:00". Se picture:

The estimated benefit was like this:

I followed the instructions on the watch and ended up with this training effect result which I thought was strange... I noticed that the speedometer had really long delays while running.

 

I logged in to Garmin Connect on the web to look at the training and especially the pace diagram which shows targeted pace vs the watch pace. And there it is, the delays are there and mess up the interval training. The gray is targeted speed and the blue line is the pace that the watch shows. Several seconds delays. See this picture:

And if we look at the statistics for each interval we can see that the pace is totally wrong...

Garmin, please fix this...

    Hi again! Today I got Sprint training.

    connect.garmin.com/.../5721516869

    I started speeding up with second beep of countdown before each interval and I got almost the same as was the prediction. I run unnecessarily fast, but on 10s sprint I can't control pace on watch, so I run on max.

    I found some bugs. In Czech language the text of TE prediction is too long and the numbers aren't visible. Next, that in HR mode is not clear, if the rest step is standing or running. And the last bug, that the desired HR in GC on some steps doesn't correspond with desired HR on watch. All is (I hope :-) ) clear from pictures. I will send it to Garmin directly.

    Received this workout suggestion today. Shorter and faster sprints than last time. These intervals will be problematic to get a good score on if i dont jumpstart the running.

    Just for fun i tried to change the target type to "Heart rate" instead of "Pace" and received the following message.

    So, this is more proof that Garmin mostly uses the Speed/Pace (and not so much heart bpm) for the anaerobic points. And if Speed/Pace is wrong, we will get lower anaerobic points.

    , how many anaerobic points did you get after that workout? Can you add a screenshot that shows pace/speed overlayed over your last picture?

    I forgot to insert the link to activity. I edited the last message. After first sprint I get 1.2 after second 2.1 and then it was slowly increasing after each sprint.

    Thanks! It seems rather easy to come up to around 2.0 anaerobic points. Then it gets harder. Will try my suggested sprint workout and post the result later today.

    Hmm, this was even worse than the first sprint interval workout. I only recieved 0.4 anaerobic points in total and all points from the first interval. The following 9 intervals gave zero AE points. Tried different length of the jumpstart but nothing worked this time.

    The strange thing was that my VO2 Max took a jump from 50 to 51. Looked at the decimals and the increase was 0.64 points there. Something is fishy.

    May I know how old are You? From hr zones about 42 I think. The hr in intervals is surely very low to achieve anaerobic score. Looks like something is wrong with your chest strap, because on the first interval You get higher hr, but even that it seems low to me. In the others intervals the hr is veeeery low, but the pace is good in all intervals. So my opinion is definitely something wrong with your chest strap, because the hr couldn't be lower with increased fatigue and same pace in all intervals.

    On the recent slow bike ride I get 0.2 anaerobic points for speeding up to 20m long hill, the hr goes from 92 to 144bmp. Many times I have proved, that if I repeat similar situations with same hr increase, I won't get more points.

    Im 45 years old, turning 46 in a week.

    I think that the HRM Run strap is working good. I have low heart rate. About 42 bpm in rest while awake, 158 as lactate threshold according to Garmin test and probably around 180-182 as max bpm. But it was a long time ago that i tested the max heart rate so maybe its even lower now.

    The heart rate was higher before the first interval due to the 15 minutes warmup and no rest before the first interval. Then there was a 3 minutes standing rest before interval 2-5. Then a recovery jog before interval 6 and then a 3 minutes standing rest before interval 7-10. Maybe this type of sprint workouts is wrong for me.

    The problem is that your HR is too high during the warm up

    Just look at honza_81 interval workout, his HR during warm up is lower than the HR intervals. And he got 2.9 aTE.
