Hello fellow Garminers!
Here is my problem.
I've used to track down my rides with Garmin Edge 820.
I've just bought a Fenix 5X. I've enabled at both devices Physio True up at Connect/Devices.
BUT Fenix 5X after syncing with a ride recorded with 820 DOESN'T calculate training effect, aerobic/anaerobic etc.
The only way to calculate them is to record with both devices, but that way i have 2 same rides uploaded.
So what's the fuss about the True up ? We have to buy a new device every 2 years?
