Fenix 6 Auto detect Lactat Treshold dont works.

I run with the Garmin HRM Dual and my Fenix 6 Pro Solar dont shows me the Lactate Treshold in the Connect App.

Anyone knows this Problem?

So i startet a manual thest this day, But it dont works.

For me it work's, it doesn't work for some time, it seems to need some history runs, but 20min in zone4 wich goes in to zone 5 due HR overshot is enough to trigger LT. I do the runs with HR chest strap I believe you will need a chest strap for LT

Oh so I run with to low HR i think thats the thing. I always trained Aerob in the last Week. So I think when i make a higher intensity Training it will work...

I just started to run with HRM-SS and Fenix 6 a week ago and after a few runs it suddenly offered me to update my heart rate zones based on the lactate threshold percentage. I think it needs to gather some data, probably your run needs to be at least some minimum length and above a certain HR for some time. Maybe there's more info about it if you search for it, or just wait 'till it happens...
