FR 645 stops to monitor my anaerobic (lactate) threshold

I'm using a FR 645 for more than 2 years. I recognize today that the last anaerobic (lactate) threshold (pace & HR) was calculated in March. I checked on the app and also the graph stops in March. It seems that from March on no values had been computed by FR645.

I rus as usual, no particular changes in my training and runs.

What happens to my FR?

nothing happened, it means it did not detect any changes in your LTRH

I've never kept the same threshold for so long time.. some minimum changes time by time.

I will try to run the test proposed by Garmin. Never done it.

Today I did the test proposed by Garmin training to find the LTRH

I get a new lactate threshold but something happened in the past months.. check the gap in the graph here under.

I hope my FR645 will continue to check my LTRH from now on as it did in the past.
