Lactate Threshold Guided Test with Wahoo Tickr X?

I have a Fenix 6X Pro and want to do this guided test to determine Lactate Threshold. However, I only have a Wahoo Tickr X and not the Garmin Chest HR Monitor strap.

Does anyone know if I can still do the guided Lactate Threshold test with a non-Garmin HR Strap? (the Wahoo Tickr X, in my case)

    Yes. And why don’t you just try it?

    Based on the very first line...  "This feature requires a Garmin® chest heart rate monitor "

    ... I would say not, but like BeneGi said, give it a try.  Although in my experience even with a Garmin HR-Dual, I have never gotten that test to work!  So it might be inconclusive anyhow (unless it errors out on your saying 'non-garmin sensor').  I have only gotten LT results from regular workouts or races. (just twice while running nearly daily with a FR945 for 2.5 years!!!).  Has always just responded at the end of test "No Threshold Detected", a few posts from others show its somewhat similiar.  Tech support didn't have a solution after working with them on it a while, seemed like a known issue.

    I've never performed the test, but I suspect that accurate HRV is required in order to execute the test successfully. Some straps support this, some do not.

    I think it may also go further than this, and could depend on your choice of connection type. For example, the Elite HRV app states that the TickR (X) is only HRV accurate when connecting with Bluetooth and not with ANT+. Maybe this is a strap limitation, maybe ANT+ (on phones at least).

    I *think* TickR X should be OK with the 6X using ANT+, but I don't know for sure.

    Accurate HR is required not HRV.

    So it doesn't use HRV inflection - as with the FTP Test? In that case any strap ought to work.

    Is there any such thing? Nothing I’ve ever come across. As far as I’m aware HRV does not produce a regular curve from which an inflection point can be inferred. Happy to be educated about HRV Inflection points of course.

    A bit debunked now, but it was a thing and I've witnessed it in my own HRV data. It happens. Whether you can depend on it to determine threshold is something else.

    I get the very strong impression that this inflection is exactly how Garmin determines FTP, despite producing figures (for me) below other FTP tests or even a full one hour average power.
