No more LTH (Auto Detect)?!

Same here, 4 weeks not a single record...

Planning on doing a guided test on wednesday btw, will see if that gets properly detected and also if that triggers future detections to work again... Other then that nothing the last 4 weeks.

I did an interval session today after deleting the running hr settings from the watch. For the first time since September I got a change in VO2max and a point on the gc graph for lactate threshold (unchanged, but a dot on the graph). However, the watch value for lactate threshold has not updated, and still shows the same value and a date of June 21st

Does your watch show today's lactate date?

No. Still showing June last year! 

Hi I can confirm that auto detecting isn't working. Today I did interval training reaching my speed for 10k and Half Marathon without LTH autodetect message at the end of the training.

A very simple question: is Garmin aware about this problem and is working on it, or not?

Garmin-Kevin

Just did a guided lactate threshold test which was detected by the watch and synced to connect (took no chances and disabled wifi and bluetooth to force a sync by cable).

connect.garmin.com/.../10561243890

Watch says 3:49 and 159bpm while connect says 3:50 and 159bpm but lets blame that on a rounding error.

Wonder if future intervals will now also lead to new threshold detections as well, will sync by cable the next few times initially to rule out the other issue where syncing it over BT/wifi didn't seem to work.

Btw, think these values are actually still off (think my threshold heartrate is higher and pace as well, based on a 10k, but would need to do a labtest to really validate current values again) but ok, lets first see if something actually gets detected from now on.

Keep us updated if in next trainings you will receive LTH updates, so I will do a LTH test to solve the problem

Yeah, will do... next intervals will be next week though so might take a bit ;)
