I have a Fenix 6S Pro and an Edge 830. I run both on a ride. Both are set up on my Garmin Connect profile, so it's using the same profile date (sex, height, weight etc) and my heart rate strap is connected to edge, while my Fenix is wrist based. My heary rate info will be the same on both devices for a ride, but for a 65 mile ride, Fenix reports 2250 calorie burn while Edge reports it as 3900. That is a MASSIVE difference! What is the cause?
