I figure this is a common question, but I wasn’t able to put together the right search terms to find anything in the archives. Is there a way to get your accumulated time in each HR zone through Garmin Connect? If not Garmin Connect, is there a way to do it with a FIT, TCX, or GPX file?
I figure I could convert the TCX/GPX to a CSV file and write a program to pull the values in to a program, but my Garmin doesn’t appear to poll at predictable intervals. Spot checking the data shows intervals of anywhere between 1 and 10 seconds. I’m not a great programmer and trying to calculate time by pulling that value along with HR may be too much of a pain in the ass to try.
