looking back at old indoor workouts on Garmin Connect, the Heart Rate graph is blank. The max & average HR's are shown in the Details box, so i was definitely using it...
these are typically sessions on the indoor rower - I just set the watch (FR210) running before i start and stop it when my heart-rate drops to a resting rate. But then when i upload the activity, i manually edit the time and distance fields to match the actual rowing time
is this mis-match between the recorded duration and the edited duration messing up the graphs, or can anyone think of another reason?
I don't HAVE to edit the fields, i can just put comments in for these types of activities, but it is nice to see the time/distance in the dashboard etc
