Hi. I have a Garmin FR910XT. Calorie burn estimation is totally off in Garmin Connect. For example, I did an 11 mile run today and it says I burned 76 calories. Any ideas what's wrong and how to fix it?
Are all your user details correct and sent to the device? Weight Height Age Gender etc did you use a HRM during activity how long have you had the device (as it may still be "learning you"
