Lactate threshold doesn't auto update

Jochem said:

Is this fixed already?

Yes, it was fixed in the spring of last year.

Jochem said:

Are you getting Lactate Threshold updates and on what firmware?

Yes, regularly on all SW after 15.xx IMHO. Of course, only when I run in 3-4 zones long and steady enough.

Same story here :-) 

Thanks, then it should work 16.17 aswell. Will check if im running long enough in zones 3-4.
My last run was:

Zone 3 3min

Zone 4 13 min

Zone 5 16 min

How long do I need to stay in zone?
Would like Lacate to auto update without having to change my running plan to add a lactate test.

Zone 3 3min

Seems to be a little short. And a Z5 is too high. Would do Z3 - 15 min, and Z5 - 3min. But should work in your case too. And I assume you use a chest strap?
