Race Predictor & Suggested Workouts off since update to 23.00

You should do lactate threshold test and set zones according to your lactate threshold. This should change the proposed pace

I don't run (i do cycling and I have 90 kg) or I do from time to time , I sow that Vo2 max on running is somewhere at 49 

This is the first rime when a garmin watch, predicts the range that I can actually run

for example 10k estimates that I can do in 49 min , and that is nit that easy for me, but my feeling is that its achievable 

For me it is the opposite

5k from 19 to 17

10k from 39 to 37

Half from 1h35m to 1h15m

Marathon from 3h32m to 3h15m

So, you should do FTP test

On bike or running?

On bike i have something around 310W at 88 kg but did not did for a while , 

I run today 

I did several ftp tests , I was more fit in the past, more w and les weight , but yes agree with you 

I'm having the same issue, e.g. my 5k prediction went from 18:41 to 23:54. It's funny, because last Wednesday I ran a 10k race in 40:23, but it's still predicting 51:33 right now (before the update, it was predicting something below 40:00).

I'm kind of hoping that it will get back on track once it gets the baseline for HRV (it says two more weeks), but maybe that's wishful thinking.

Other stats like VO2Max and Training Effect seem to be correct.

Did you check LHR and threshold pace?

Yes, it was last detected last Tuesday, August 30. 165 bpm and pace 4:16 min/km.
