I am using an Edge 530 riding with a Wahoo Kickr trainer on Zwift. I recorded a workout simultaneously with the 530 on Indoor Cycling and on Zwift to compare the results. I was surprised to see that the training load was quite different between the two. I've done this twice and both workouts had significant differences. For Example:
Ride 1 - Sept 30 - Zwift training load 535 / Edge 530 Training load 214
Ride 2 - Oct 2 - Zwift training load 329 / Edge 530 training load 176
I'm confused by this as from what I understand the Load should be calculated on the 530 in both cases and both data sources are recording the same information from the same workout. Has anyone else seen this or know what is going on?
