We start every day at around 10:00 in the morning and we come back to our hotel between 3 and 4 in the afternoon. That means you have to be able to ski at least 20 to 25 km each day, either classic or skate. Each day there will be choices so that if you are super tired, you can pick an easier and shorter trail. Also, there are numerous possibilities along the trails for you to stop to rest. The highest-level groups will ski up to 40 km each day, but you certainly do not have to. Everybody gets to take their lunch with them.
