Huge difference in exercise load between MTB and gravel bike.

Hi, I have an edge 1030 and a forerunner 965. If I go ride my MTB, they have a simular exercise load. If I go ride my gravel bike, the exercise load of my Edge 1030 gives double the number of my watch. The watch gives me what I expect, and the Edge 1030 is completely off. It messes up the chart of my training load and makes my edge useless. Both my watch and edge are connected to the same heartrate band. My watch uses GPS and my edge a speed and cadance meter. My watch usually gives me 5% more average speed. I ride on a different profile on my edge 1030 when i go out on my gravel bike instead of MTB.

Hi, as a caution, are you recording the *same activity* on both devices at the same time, in the same user account? That can mess up your metrics because it appears as 2 activities instead of one (and one device's result may be influenced by it being "the second activity" that day). Could be a factor here.

All that said, Load (or EPOC) comes primarily from heartrate data and your %VO2max. Physio TrueUp needs to be enabled on both devices to ensure both are using the same VO2max (and everything else, especially MaxHR). Then it shouldn't matter which bike you ride or which device you use, if you are doing the same %VO2max (ie the same HR), then you should be accumulating Load/EPOC at the same rate. If it's an identical ride on both devices then they should end up with the same Load (and also the same Training Effect).
