Don't elite xc skiers traditionally have the highest recorded VO2's?
This is true and I obviously agree that skiing is very good training.
However, from my experience, a 4 minute VO2max interval hurts more on the bike than it does on the skis even though the oxygen consumption is probably higher while skiing. Yet the lactate build up is more intense on the bike, since basically only the legs and lower back muscles do the work and the lactate accumulates there. On the skis it is distributed more evenly.
On the other hand, my heart rates are generally higher while skiing. If I do 1hr (or 3x20min) threshold workouts on the skis, I expect to average 185bpm for the interval. I couldn't hold that for 5 minutes on the bike.
Two more skiing days left, 40 wonderful moderate intensity kms apiece.
