The marathon starting point is at the former sulfur mine. The route starts with a pronounced climb of about 400 meters difference in level, following the winding road marked with blue triangle, the forest secular living in intimate admixture species of spruce and swiss pine. At the exit to the alpine plain, the trail continues to the right, leaving the Rețitiș peak to the left and reaches the Șaua Nicovala (1,934 m) - the highest point of the route.
From here a straight line is kept, bypassing the tip of the Vârful Pietricelului (1,993 m), intersecting briefly the Trans-Călimani trail, until the Ilva dirt heap, from which a short descent starts to the Șaua Negoiu (1,705 m). From here, on clear days the Fagaras and Bucegi mountains can be seen in the distance. Basically, at this point, the route overlaps the Maria Theresia path. The route continues with bypassing the tip of Negoiul Unguresc and Pietrosului with a short descent to Poiana Monor, from where an accentuated ascent follows till Culmea Piciorului Monor, from where there’s another difficult climb to Poiana Izvoare (1,723 m). Follow a steep climb to a place called “La Troiță“. From this point the trail becomes easier bypassing Cozii Pietrosului and reaching Monumentul Eroilor de la Grui (about 1,800 m). On the same level at about 1,800 meters the trail goes under Ciungetu and Ruștii peaks, from where we can admire the 12 Apostles. From here a smooth descent follows over a distance of more than 2 kilometers to the beautiful opening, Poiana Arsuri (1,673 m). The route enters the shadow of a spruce forest, climbs through a relatively short but bumpy field, then continues on the trail to Poiana Piciorul Ilei, returning soon to the level of the spruce forest, under Stracior tip. After approximately 1.5 km you reach Strunior Glade (1,650 m) and after crossing the opening the route re-enters the spruce forest, on the same curve. Over the next 4 km of trail there are no significant differences in level, the land is relatively flat. The trail reaches the Dălbidan glade, then the descent continues to Poiana Treha, followed by a short ascent of about 800 meters up to the top of Buba (1,670 m). Through the spruce forest the trail then descends into two groves: Poiana Ciunga Vădanei (1,406 m) and Poiana Prelucilor (1,265 m). Here starts the ascent to the top of Cornului (1,502 m), which it’s not reached, as the trail is entering a different curve. The next 1.5 km of the trail is descending slightly through the forest to an opening with a sheepfold. It follows another slight descent and a short climb, leading to Cantonul Silvic Tihuța Colibița (near the Piatra Fântânele village) – the finish line of the race.
