Had you asked me I would have said that Fiskartorpet GP was much easier than Knivsta GP. The CP curve below tells a different story.
Fiskartorpet CP curve above shows much higher intensities also a bigger area under the curve.
Knivsta, which felt much more intense doesn’t look as hard. Lower top end.
This tells me that the time in Z5 is what is killing me. Top end seems to be ok.
More thinking required.
