I got for some time wrong heart zones in my user profile so some activities result with wrong heart zone time attribution.
Now i fixed the zones at the correct levels but the attribution seems to be done at .fit file creation time.
Exporting the file from Garmin Connect, deleting and reloading does not change anything.
I downloaded the file in tcx and gpx format but I did not manage to see how zones or time in zones info are stored.
Any clue???
Thanks...
