Never gotten Lactate Threshold estimate in over 2000km

The watch has never given me a lactate threshold estimate. I have been running with it for more than 2000km now, always using a HR chest strap. I have also tried to take the guided test once, but after I completed it, it just said that it was unable to give me an estimate or something like that.

I have used the watch for all kinds of running. Slow long runs, fast long runs, intervals, you name it.

This is even my second 945 after my first had a software bootloop. Neither watch has ever given me an estimate.

Any tips?

Are your heart rate zones accurate? E.g if you real max hr is 160 but in your watch 200 you’ll never get a estimate because you have to run close to your max in the final steps in the guided rest.

I have not had a lab test, but my HR zones feel fairly accurate in training. My max is set to 205 and i did reach 203 this last fall in a short uphill race. I regularly hit around 195 in hard workouts, so 205 seems to be a fair estimate.

have you switched it on to be messured automatically ?

I forgot to mention, but yes I have.

It needs a run with steady effort periods ranging from just below to just above your threshold - that's what the guided test tries to achieve by getting you running at a increasing set of paces.

I'd suggest trying the guided test again a few times over a few weeks.

I gave up trying to get the lactate threshold test to succeed - same issue as you - max hr set to default for my age

Did you manage to get it working in the end?

0 MikkelEB over 3 years ago

No, I never got it working. I have not tried the guided test more than once though, since it is a silly workout that interferes with my normal training program, so I am not willing to try it several times hoping for it to work.

I have also used several different chest HR monitors over the last three years, including the Garmin hrm run.
