I have a Tom Tom Multisport and have noticed that on the same run when I always wear my garmin vivomove hr, the calories burned difference is massive and I don’t know why? I have been through all of my personal setting to make sure that they’re identical and they are yet this morning my 8km run tracked at burning 497 calories on my Garmin and my Multisport at 1049 calories burned. Does anyone know why this happens and if I can do anything to resolve it. Thanks in anticipation!!
