At the Olympic cross-country skiing venue in Tesero, a series of wax trucks, likened to a traveling circus, stand along the banks of the Avisio River. These vehicles include the host country's Italian truck, Norwegian and Finnish dual-level giants, and a strategically placed Austrian truck, next to three German trucks complete with small terraces resembling campsites. Inside these trucks, technicians, known as waxers, are busy preparing skis for optimal performance by applying wax and using machines for fine-tuning, highlighting the importance of ski maintenance in competitive skiing events.

In an interview with Enrico Heisig, the Chief Technician of the German Ski Association (DSV) and head of the technology center in Oberhof, he explains the necessity of having three trucks dedicated to the German cross-country skiers and combiners for waxing and grinding purposes. He notes that each truck serves a specific function: one for cross-country skiers, another for combiners, and the mobile grinding workshop currently being discussed, which plays a critical role in maintaining the skis' performance by ensuring they are finely ground.

This intricate operation underscores the advanced technology and preparation behind Olympic level ski competitions. The setup and efficiency of the wax trucks not only affect the athletes' performance but also embody the elaborate efforts that go into securing competitive advantages in winter sports. With waxing and grinding being such detail-oriented tasks, the trucks represent a blend of skilled craftsmanship and technological innovation crucial for a successful Olympic experience.
