Former Member over 7 years ago

Hi,
Is there anybody for who LT auto dectect works ? As you could see on my Garmin connect's screen capture i'm superman. Of course i always run with HRM chestbelt and auto detect is on.
Any advices ?

Nobody seems to use the function :(

I did it by the past, it's not hard. Just stay in the green zone until you couldn't. Here the watch was unable to set a LT.
More of a bug or hardware problem, one more. See here : https://forums.garmin.com/forum/into-sports/running/forerunner-935-aa/1297381-lactate-threshold-too-low-heart-rate
The watch is going to return at Garmin.

it has something to do with the update to 7.60 , since my lactic threshold also changed to 46bpm (the exact same value as different other users) .
The last automatic-measured value (before i updated to 7.60) was 179bpm. After the update, i got high intensity-minutes for a normal run (and 57hours of suggested resting time), after the same occured at the second rund two days later i had a look at the lactic threshold and found it @46bpm.

I just deleted the userprofile for run, under the option-menu "heartrate" on the watch itself (i cant remember if i created this userprofile on my own or if it was already there) , changed it to many different values manually, synced, changed, synced.... now it remains at 179bpm on garmin connect mobile + online ... no matter what lactic threshold values i enter on my watch, the values in garmin connect mobile and garmin connect online do not change at all (always 179bpm) no matter if i sync via bluetooth and/or wifi . . .I am curious what will happen to the lactic value after my next runs.

I called the support and they took me for an idiot. For them it is because I do not use a sensor of their brand and they do not want to take care of it under guarantee. This brand is a swindle.

just to say I got a lactate threshold detected last night. It was on a 935 but the software closely matches the F5. It was during a track session 'diminishing returns'. 300easy, 100hard, 200easy, 200hard, 100easy, 300effort, 400easy, 400effort. Repeat for 30 minutes.

You're a lucky guy. I tried to set manually a LT value but the watch came back to 46 bpm after my last run 10,43 km 4:28/km.

Somebody knows if it is possible to return to an older version of the OS (i'd try the 5.84 os beta version) ?.
Here we can find all versions : http://gawisp.com/perry/fenix_D2_tactix/

mine looked fine 4:04/km 158bpm (max is 174)

problem solved (for me): i deleted the HearRate-profiles for running, swimming and cycling (as mentioned in the posting #13 above) and did a normal run but with a longer sprint at the end, to get above my lactric threshold heart rate. And everything went as expected: new lactic threshold value autodetected: save and accept as new values?:yes .
problem solved for me. (the heart rate profiles are also there again but only running is filled with the correct new values)

Ok thanks. I'll try. Did you also turn off this heart rate profiles in GC app?

0 jupjap over 7 years ago

i learned, that it can cause many problems to modify values/rates/profiles on the watch AND on GC-app/GC-online. Only change it on the watch itself and then sync two times.
Best regards, Thomas

Alléluia ! In community we trust not in GarminSupport. I followed your advice and it works! I have again a little bit low detected lactic threshold I find but I ran slowly and accelerated over the end. I hope that for my next running that will work again with a more realistic result. Thank you again jupjap and the others guys.
