Treadmill Run Updated Running Lactate Threshold. Why?

mip 2 months ago

I did an hour on the treadmill this morning and at the end of the workout I was presented an updated Running Lactate Threshold screen. The update also appears in my Performance Stats. As I understand it, this should not happen (especially as the treadmill was at a 15 incline the whole time) - so why did this happen?

And your opinion is based on what?
Regarding this: https://www8.garmin.com/manuals/webhelp/GUID-C001C335-A8EC-4A41-AB0E-BAC434259F92/EN-US/GUID-3ED97FFE-025E-47EA-9C70-DD86156617BD.html, your watch behave as it should, if you use HR sensor, pace was measured, LT auto detection was enabled and you exceeded 90% of your MaxHR watch just did what was expected.

Pretty simple: a treadmill activity obviously does not have GPS enabled and is not an outdoor activity prodile.

Requirements for Improved Lactate Threshold

Your watch will auto detect a reading when the following conditions are met:

Have an established VO2 Max estimate.
Perform a GPS enabled run activity using an outdoor activity profile such as Run or Trail Run.
Use the optical heart rate sensor on your watch or a paired chest strap heart rate monitor to record your heart rate activity.
Have auto detection enabled for lactate threshold. This setting is enabled by default.
