I used to have the option to do a Guided Lacted Threshold test on my Phenix 8. It was under the Run activity, as one of the options of the Workout Library.
I recently updated to 12.22 and now I can't find it,
On my next to previous run, it overestimated my threshold. I'm glad that it thinks I can keep that pace, but I can't. So I shifted it down manually a bit. I don't know if that has anything to do with it.
I've run the test in the past, and I wanted to run the test again, and yes I do have a chest heart rate monitor.
I know it will automatically calculate it on runs, but like I mentioned above, on a recent run, it just over estimated it, so I just want to do a specific run for it.
