    I'll do ya one better... have had my watch since early summer, never have gotten a Lactate Threshold (heart rate or pace) to show up!  lol

    You getting regular updates to it during strong workouts?  Similar to how vo2max is shown?

    Are you making use of a  HRM chest strap? This is required for lactate threshold to be calculated.

    yep, with Garmin HRM-Dual on every run.  I have a tech support ticket on it, sounds like it could be a known issue.  Waiting for further help or a fix

    will update if i hear anything back.  I am suspecting that it is expecting my HR to get higher maybe.  Here is some of the notes from the first line tech support guy in response to some questions I had.  Interesting his test ended mid way through a segment (less than a minute into final segment?!), mine have always went a full 3min of me fading...before saying 'fail to detect'.  Also in another question he mentions getting threshold detected on strong workout days also.  Who knows...

    It is detected similar to how vo2max and bike FTP values are detected?  Or does it require a full gas, burnout, ramp test to pretty much failure like the guided threshold test?  I don't think the LT test should TOTALLY gas you.  I remember doing mine about a month ago and the watch only had me stay in Z5 for 45-60 seconds.  I was pretty tired at the end, but probably could have stayed in Z5 for another minute or two at that same pace.

    Shouldn't threshold HR and pace also be detected during regular runs and strong workouts?  I have my HR Zones set to '% of LTHR' rather than '% or Max HR'.  I will see new LTHR and LT Pace levels detected on intense runs, usually on Speed Training days.  I have also though, gone months without an update.  Those updates also include either the LTHR or LT Pace lowering, not just raising.

    That's unfortunate/odd. I'm using the same setup without issue so far.

    I wear an external HRM on all my runs and I rarely, I mean really rarely, ever get a LTHR reading.  But a week ago I finished a run with a 2min sprint where my HR climbed into upper Z4 and just a bit into Z5.  I was surprised to see both a LTHR and a LT pace set for that run.

    Of course, the pace was out of whack because the sprint was uphill but the LTHR was around where I'd expect it to be.
