The start will take place-as per tradition-at the green area of the Sondalo Multipurpose Sports Center, the logistical base of the entire event. After running, in the meadows, 1 km flat, the roughness begins:

immediately a first climb of 200 m D that leads to the locality Tobai, following a first part of asphalt road through the historic center of Sondalo and a second trance of the route along the old mule track that runs along the walls of theMorelli Hospital, the former largest sanatorium in Europe and a monumental heritage site. The trail begins to flatten out and a beautiful singletrack leads to the locality of Valena followed by a short descent to the hamlet of Sommacologna that will make the athletes regain energy in view of the next climb that, on a short scenic trail, leads the athletes to the huts of Remoscol. From here the trail crosses Val Ferera and, passing through La Piada, the run continues to the locality of Li Vedagoli, from here short ups and downs lead in the vicinity of the huts of Val Ferera. Following the Dozzy Trail, a nice path in the woods skirting the Foppa hut with 250 m D, you arrive at the firebreak; now a km slightly downhill, on a dirt road, takes athletes to the Meler huts at an altitude of 1400 m (refreshment point). Another 800 m singletrack in the woods joins the Colonie road, a vantage point with breathtaking views of the valley floor, and continues with a descent, on dirt road, to the Solezzo Alto and Alberghetto localities, where a 300 m runnable falsopiano begins. Here begins the nosedive to the finish, with a succession of spectacular trails (theater of Sondalo Bike Day), which will take riders first to the magnificent Art Nouveau complex of Pineta di Sortenna, Italy's first sanatorium, and then to the localities of La Capretta and Vallesana. The descent continues until reaching the promontory with the ruins of the ancient Castle of Boffalora and, a few meters later, the panoramic spur overlooking Sondalo where the small Church of S. Agnese, a heritage site, stands. The last meters before the finish line are run on a comfortable path (avoiding the steeper passages of the last editions) that leads to the bridge of S. Rocco to continue with the last 500 m of flat ground leading to the final rush and the finish at the Sports Center
