Of course the intensity matters here. As I am using Polar device to record HR during workouts, I also checked from Polar Flow the values. In this case XC skiing was more than double on cardio load estimate. TrainingPeaks did not seem to reflect to this at all.

And I was going with classic style on relatively flat ground trying to stay on Zone 2, but uphills and downhills drifted the HR out from this zone.

My HR threshold was determined by lactate running test in a laboratory so that should be pretty accurate. It was some time ago though.

I am planning to do the test as defined in the training plan soon – as soon as outside temperature drops a bit.

Still I am confused how XC skiing could seem so close to walking.
