I've been studying XC skiing in all its forms for decades -- studying, enjoying, reveling-in, playing-with.
These here are my teaching notes for CLASSIC SKIING -- striding -- regular XC. I posted something similar for ski-skating. Indeed, I'm only replacing the skate-specific stuff. A lot of this applies to both styles. And even to other skiing like telemark and alpine.
So as you might've noticed Classic skiing is the typical, traditional, all-round type of skiing that you can do anywhere. It might be called Striding or Touring. For ski-skating you need a wide machine-groomed course. So wide that it's not really a trail anymore. Yet you can also do skating anywhere the snow is firm -- so whenever the snow melts and freezes a few times you can get a strong enough crust on top that would let you skate-ski anywhere. Then you know what to do!
