Lactate Threshold - how to trigger?

I have had my 945 now for about 2 months but my Lactate Threshold measurement is still empty after all this time? Does anyone know how Garmin suggests we trigger it? There isn't anything in the 945 manual that I can find.

Why not just di the test:

Open the run app, press up, select training, scroll down to LT test.

So I've had my 945 now for 3+ months, run all sorts of miles on it, including races and it has never triggered a lactate threshold result, even with that autodetect setting as "on."

So I…

Probably because I didn't know that was in there! Ha ha.

Like I said, there isn't anything in the 945 manual about it as far as I can tell.

Actually I just did a google search and found it in the Fenix5 manual, and it's in the same place under the 945 manual.

Doing the test will fill it. But also any run that increases in speed over time tend to trigger a measurement for me.

Thanks. Can you tell what the basic test protocol is? I want to try it but I need to know if I need to have a long flat section and how long it needs to be.

Okay smarty pants, I had already googled it and came up with no answers (only how to get to get it in the garmin menu system). I just want to know the basic protocol (i.e. warmup for 15min, run for xx amount of time, cooldown).

If you read my post you'd know why I wouldn't want to just use my watch, I live in a hilly area, most tests require a certain amount of flat course so I'd like to know if I need to plan for that.

Yes there is.

Do Fartlek's.

If you ask what? https://en.wikipedia.org/wiki/Fartlek

And they are more enjoyable than the LT test in the watch :D

So I am finally going to run the actual test and see what it has to say. Incidentally no one here was able to tell me what the actual test steps protocol is, I found it elsewhere (I think it was the 935 forum where someone else asked the same question). Looks like the whole thing will take less than 20 minutes and course difficulty plays a part, so finding flat miles are important.
