Performance condition, LT not updated for 2 years

The last time my watch showed a 'peaking' training status was April 2022. Almost 2.5 years ago. I now go between productive, maintaining etc but never reach peaking. Since then I've achieved several pbs on a variety of distances including the marathon. My predicted time for the marathon on my watch is 12 minutes slower than I achieved a few months ago.  I do speed work twice a week, long runs, races, parkruns, easy runs, weight training etc but nothing gets me back to peaking.

April 2022 was when I had another issue with Lactate Threshold on my account never updating. It still has nothing - just a blank graph. My Vo2 used to go up or down one depending on a race or fast parkrun. Nothing changes. My vo2 dropped one when I had a few weeks off with a broken toe but has never climbed back up.

I train 6 days a week. Fitter now than 2022 albeit 2 years older but I can't understand why I am missing so much personal performance data or it just never updates. I have asked this a few times over the two years, had the watch replaced even by Garmin and been through all the resets etc. I can't seem to get an answer on this. Anyone else?

I know many will say that the stats are just numbers and not like a real vo2 assessment however they used to work and now they don't and it's been two years. It was a good idea of how fit I was even if the numbers were not perfectly accurate.

Other things that have stopped working:

I used to get a + or - number flash up about 15 minutes into a run to show performance condition. 

I would get a message to say how many hours of recovery were suggested

Another message to say how a restful day has improved recovery time to x 

I purchased the watch in April 2020 and received a refurbished one approx 2 years later. 

Does anyone still get these notifications and adjustments to performance or have they been wiped with software upgrades?

Other than timing my run and GPS for such an expensive watch I don't seem to get any of the features as advertised! I haven't changed any settings.

  • If it takes about 15 minutes to show performance condition then it looks like you are not doing a meaningful run and the watch can't get sufficient data to make an assessment.  Usually it should start recording performance condition at 6 minutes if your heart rate is elevated enough.  Also use a heart rate strap if possible - wrist based is not good enough for running.

  • Maybe it was sooner into the run - I can't remember it's been that long since it showed up. Ran 30 kms on Sunday. parkruns around 21 mins weekly. Interval sessions twice weekly which are usually 10 km all in with warm up and cool down. Except for parkruns all my easy runs are 40 mins plus. All enough data. I haven't done less than before when these metrics did show up.  I wear an HR chest strap for most runs. 

  • A 21 minute parkrun should definitely be enough to show performance condition at the 6 minute mark.  If you look at the reports on garmin connect on a PC are you getting any data on the long term graphs for LT?  It doesn't get updated after every run - only when you push hard enough.

  • Last time my LT recorded was January 2023. All graphs since have no data yet I wear the chest strap and run around 75 km a week. I've pushed plenty since then. Sydney City to Surf (14km) last year in 61.03, marathon pb 3.18 in March. Nothing impresses the watch!!  

  • Check out the Max HR. If it is set too high, you may not be reaching the requirement of staying minimally 10 continuous minutes above 70% of the Max HR.

    After you have checked and adjusted the Max HR to match your true Max HR (not the highest HR you ever achieved, though !!), then I recommend conducing the Self Guided LT Test found in the Training menu of the Run activity profile.

    Also double-check that the LTHR auto-detection is enabled.

  • Thanks for your reply. When things first stopped updating on the watch 2 years ago I bought a chest strap and did the LT test. It said no LT detected at the time. I have just checked out my heart rate zones. They were set to base on my LT which has had no data all that time. I've set it HRR and put in my resting HR and reset the zones. My LT threshold is set to auto detect on the watch it just doesn't do anything. I have a race tomorrow will see if anything adjusts. Thanks 

  • The HR zones, as well as the Resting HR are in fact unimportant for the LTHR detection. What is ultimately important is the true Max HR. If the LTHR was not detected during the self-guided test, it was almost certainly because of a too high (or perhaps even too low) Max HR value. Make sure to enter the right value. The auto-detection may also easily fail and enter a wrong value. It is better turning it off once reliably established (Max HR does not change with fitness, it only decreases with age). Do not rely on the formula 220-age, and do not enter the highest HR from your stats. That's not the Max HR. You must be able to sustain the Max HR up to some ~30s. Best detected in a lab, or in a field test (search YT - there are plenty of tutorials).
