Issue with 19.10 update

Most of these metrics look at your HR as a percentage of maxHR. Unfortunately maxHR can sometimes get screwed up after an update.

Change your maxHR in Garmin Connect to a different number, then sync it to the watch. (You may need to switch to a different zone setting method to do this). Then change it back in Garmin Connect to the correct number, and sync again.

Thanks for the reply. Unfortunately, that doesn't appear to be the problem. The zones appear to be correct, as does the max heart rate.

Regardless of them appearing correct.. did you change the maxHR value, sync and change it back again? 

Still waiting for this version... (I'm on Beta 18.80) and it looks OK

I will reinforce mcalista suggestion. I've also previously got HR zones messed up without apparent reason. Recorded activities would not reflect aerobic effort. After fiddling a lot I've found that changing HR zones to something *new*, syncing and then changing the values back to what was there was the solution.  

I misunderstood. I'll give it a shot now. Thanks!

Thanks for the advice. I'll try it today and report back.

Unfortunately, it didn't work. Still showing 0.6 aerobic benefit from a 5 mile, 34 minute run.

I tried and unfortunately, it didn't work.Thanks for the help though.

i am on 19.10 and training effect with a power meter cycling works fine. I just upgraded from 12.20 and did not change a thing.
