The progenitor of the DXT trails kicks off the event in 2013.
The 55K is an exciting ups and downs between woods, rocks and uncontaminated scenery. It will be the Dolomite landscapes to give you the joy of running, thinking about the route you have already covered and keeping your eyes on the goal.

Departure from DXT Village in Forno at 850 m above sea level.
After the initial 2 km that lead to the Pratoront plain, you reach Pralongo at 1000 m above sea level (3rd km); near the church, take the road the uphill forest-pastoral road the uphill forest road that reaches the Pian dairy farm, where it joins the 103K route, then the Vach lake (6th km). Continue under the slopes of San Sebastiano on a single track up to the first refreshment point of Passo Duran (11.6 km time gate).
Here begins the most demanding part of the route with the tough climb to Bivacco Grisetti (2050 m asl) and the equally demanding descent towards the Malga Grava refreshment point (18.5 km), followed by the crossing at the base of Monte Civetta, the descent to the Palanche refreshment point (23.5 km) and the steep climb of about 3 km to Malga Pioda (refreshment). Continue on meadows and grassy slopes towards another refreshment point above 2000 m, the Belvedere Refuge (30.5 km), before arriving at the life base of Passo Staulanza, second time gate (37th km).
Now the undulating path, sometimes muddy, runs at the base of the Pelmo massif up to the Passo Tamai refreshment point (44th km); from here two short but hard uphill stretches that lead to the 1950 m asl of Mount Punta, a spectacular panoramic point over the whole of the Zoldo Dolomites which is followed by a regular descent of 6 km on a military road up to Casal.
The last 2 km on asphalt cross the villages of Bragarezza, Pra, Sommariva and Campo and finally the finish in Forno.
The total altitude difference is about 3600 m.
