Lactate threshold always “jumps back” to 155 in GC

Former Member over 5 years ago

I have a Fenix 6x pro and I have done two guided LT tests on my watch about a month apart. My first set my LT to 171 and the second to 170. Anyway. After I have run the day after my LT in GC always goes back to 155 and stay there. My watch still says my LT is what it was after my test and it does not show a new one after a normal run. It’s very strange that my LT is reduced with 15 beats in a day?? My LT tempo is not affected though only the LT BPM. Anyone else with this issue?

Screenshot in Swedish but you can probably see the strange graph and LT value in the bottom.

Maybe because you also have 2 LTs? See my story here https://forums.garmin.com/apps-software/mobile-apps-web/f/garmin-connect-mobile-ios/238485/lactate-threshold-chart-bug-ios-mixing-cycling-and-running-lt

You can have two LTs also in that case if you manually typed a LT for the general HR zones, running HR zones or cycling HR zones.

It is the reason why your LT pace did not change, because LT HR of 155 is linked to not running, but is assigned to cycling or generally to sports.
