Teams in the field erect protective fences along the course and in the finish arena.

The protective fences along the course and in the finish arena are very important for the athletes themselves, as they protect them from crashing into trees or structures in the finish arena. This is because athletes take to the track uncompromisingly and at very high speeds, and even minor mistakes can happen that throw them off their ideal line. Fences along the course keep them from slipping off the ski slope.

The installation of the fences is planned for the Wednesday and Thursday before the race.
