Suggested workout HR for cycling seems low

Does the fenix 7 have automatic calculation of the anaerobic threshold for the bike? as well as ftp?

I have started to use the daily suggestions for cycling and I have the same problem.

Here I put the suggestions for this week for cycling and running.

Cycling
Base - 1:30:00 109bpm 100W <- This should not be Z1, it should be 133bpm 120W
Base - 2:54:00 109bpm 100W <- This should not be Z1, it should be 133bpm 120W
Base - 1:17:00 109bpm 100W <- This should not be Z1, it should be 133bpm 120W
Threshold: 46:00 Warm Up 15:00 133bpm 120W 16:00@162bpm 180W LOOK THE WARM UP HERE, IT IS CORRECT, IN Z2 RANGE
Recovery - 30:00 109bpm 100W This  is correct
Threshold: 46:00 Warm Up 15:00 133bpm 120W 16:00@162bpm 180W
Base - 1:17:00 109bpm 100W <- This should not be Z1, it should be 133bpm 120W

Run (Run zones and paces are correct in running)
Base - 45:00 137bpm 5:45
Base - 40:00 137bpm 5:45
Threshold - 39:00 Warm Up 10:00 137bpm 5:45 19:00 162bpm 4:35
Base - 45:00 137bpm 5:45
Threshold - Warm Up 10:00 137bpm 5:45 3x7:00@162 bpm 4:35
Recovery - 32:00 124bpm 6:30
Anaerobic - Warm Up 15:00min 137bpm 8x1:00@3:50

Chirs, Could you give a look to this, it seems an SEVERE  old bug still present on 11.25

Please fix it and add primary race for cycling for daily suggestiion to work for primary races.

Hi,

I have Fenix 6 and started following the suggested workouts for cycling about a month ago. I have similar situation to you: base and recovery workouts have the same target heart rate (113 bpm), which is below lower bound for zone 1 (121 bpm, based on % of hrr).

Did you continue to follow the suggest workouts and did the target normalize with time?

Sadly no, I completed a 4 months plan and it never normalize. I always did the suggeested workout for the day and I did not pick workouts in other order.

For me there is other major flaw and it is the recovery time in bike suggested workouts.

Even with Z1 workouts the recovery time is excessive and a lot of workouts are replaced for rest days or reduced at half or more.

Because that, the accute load was always at bottom of the green bar, barely maintaining 'maintaning status' and Vo2max lowered from 55 to 54.

I do not recommend to follow daily suggestions to prepare a race.

Having the same issue with the cycling suggested workouts on my quatix 7 pro. Using %HRR for both running and cycling where running suggestions works just fine.

Garmin-Laurie  could you help us with this problem? You have permissions to view my account, would you need me to send any files from the Fenix?

I am giving DSW a second try for cycling but the same thing keeps happening as two years ago, the base workouts still have a heart rate below zone 1 but it gives a recovery time as if it was a z2 workout. 

Every workout since the beginning has been 108/109 bpm.

This is my DSW for this week which has been very similar for the month and a half I have been following the plan.
