I just got my first apple watch (2) about a month ago. The activity readings, especially during an outdoor cycle session, are really off, and I'm hoping it's because I've failed to do something obvious (otherwise I'm regretting my purchase!). I've been on several outdoor cycle sessions and they're grossly off in terms of miles, speed, and calories. I know this because I use my Garmin Edge 820 with heart rate monitor strapped on for comparison. For reference, I use Open goal on the apple watch, and when finished I save the activity. Recent example: Garmin Edge 820 Apple Watch Distance 22.96 miles 6.16 miles AvgSpeed 12.4mph 3.1mph ElevationGain 1207 ft 1007 ft Calories 1362 total 1014 total (814 active) From what I understand, for activities like running or indoor training, calibration is necessary to fine tune heart rate/calories burned, but my concern is the GPS data is WAY off on these outdoor cycle readings. What am I missing? FWIW, the watch also regularly fails to register my daily dog walks as exercise. I've assumed maybe that's because it doesn't get my heart rate up enough, but again shouldn't the GPS discern that I'm moving? My old Polar watch was a better daily fitness tracker than this watch so far.
