Other then trainer powermeter
I've noticed that the saved activity at TP shows the trainer power data and not my pedal or crank powermeter when i choose them as preferred during my TP Virtual ride. I didn't find any way of change it.
It should save the powermeter data that we choose as preferred power. Thanks

Many thanks for your suggestion and support for TrainingPeaks Virtual.
The FIT files already include both the trainer power and powermeter power (a true dual-recording single file!), however not all 3rd party platforms can read this yet. You can however view all the data in applications like Golden Cheetah, or https://dualrecording.com

Many Thanks! Nice to know the dual recording option to analyse differences
But, what is the Training peaks upload data form TP Virtual since it only has one? Is the one i choose as preferred in TP Virtual?
Thanks
