Open, 6º at 6 am, clear skies. Forecast high 25º and sunny. 25 km open, 25 km classic and 6 km skate. Great track, hard pack skiing. Snow late today and tonight.
Carry a knapsack. If you overdress you can carry your extra clothes.
When Nordic skiing we all warm up quite a bit. So that makes it a great sport for cold weather (No chairlift). Sweating does happen. A dry shirt to wear for your second lap and/or to wear home is really nice.
