Performance condition/anaerobic not working anymore

My Fenix 6 has stopped recording anaerobic work and I never get a performance condition. The widget never come up anymore and even with a tough workout in all zones my training load is in 20s and never any anaerobic number! I use a power meter and heart rate strap and used to work fine but suddenly every ride puts me in recovery and my load is just dropping off. Vo2 won't change either and my rest should always be way more than it says.

Any ideas as to why? I can't for the life of me figure this out. Heart rate zones are the same and power zones are.

Idem

Mine too. No anaerobic since 19.20 beta and release

Hmm... I had a hard run yesterday with 31% of time spent at zone 5 and my HR reaching 95% of the max. Still there was zero anaerobic impact according to Garmin Connect.

Fw 19.20 all working as it should.

Interestingly enough it worked on today's run. I spent 11% of time in zone 5 and got 2.5 anaerobic training effect. But as I mentioned I got zero anaerobic training effect two days ago while I spent more time in zone 5.

This was a run this morning with 19.21b although not seen any problems with 19.20 -connect.garmin.com/.../7502580176

Performance Condition came up during the run. Heart rate from the wrist.

Garmin checked my data on some activities and said they need to investigate this further now. Hope they can sort it

Was the Pace about the same on the two runs? I mostly getting my anaerobic points when i run fast for shorter periods (intervals), for me its not so much about getting the HR to zone 5.

Yeah, this is a good point! The first one was a hard but steady effort, and I didn't get any anaerobic points. I haven't fully recovered from a 100 miler that I finished less than 3 weeks ago, so my HR is still higher than usual.

The second one was a moderate effort run but I pushed hard on two Strava segments. So in a way that looked more like intervals run.

Also, the first one was a trail run while the second one - a road run. I don't know if that matters.

There are a built-in data field that shows both aerobic and anaerobic points during a run. Try that one to see when you get the points during the runs. I learned that way and intervals works best for me. But, I'm having trouble to get 3+ anaerobic points. Need to dig in that later on... haven't tested with 19.20 yet though. Road runs are probably faster than trail runs but I don't know if the algorithm for anaerobic points differs between the Run, Track run, Trail run activities. Maybe there are differences there.
