When I’m free skiing I don’t use quite as much power on every turn as I would in the gates so I can last longer. Again, my endurance isn't any better I’m just using my energy more efficiently.
Fitness is important, but it’s not the only part of the equation for endurance on the hill. I have to agree with those that say it’s not possible to ski “on the edge” all day. I can’t do it either, and I’m fairly focused on ski fitness (ride 5000 miles a year, lift weights from October through March, and on snow 3 days a week throughout the winter).
But cruise easy blues on a GS ski while working on a specific technique or balance exercise=no real demand.
I'm big on pre-season anaerobic threshold training, long sets of jumping exercises and interval training ,to simulate the anaerobic demands of high intensity skiing. (There's a long set of stairs up the hill near my house. You can jump up every other step in just over a minute and then jog the long way back down over streets for five minutes.) That anaerobic threshold endurance seems to take a big hit if I haven't been training.
