The course consists of two loops through the Southern Chiemgau. First is a 26 k loop around Rauschberg mountain, followed by a 74 k loop around the Hochfelln massif and up to its summit. The accumulated climbs amount to about 4400 m (13 200 ft). Large parts of the course employ narrow alpine hiking trails, so you should have a safe step and be free of acrophobia

Starting at the Stadium in Ruhpolding you run on easy terrain via Infang, Froschsee and Schmelz (A) to Zwing (A). From here follow on narrow hiking trail "Alpensteig" (Caution, risks of lethal fall!) up to the Kaitel Alm (K) and further on good forestry roads down to Laubau and back to the Stadium (V,K,A).
The second loop begins with a long climb to the Unternberg saddle via Stockreit, Weingarten, Raffner Alm and up the ski slope or the hiking trail to the saddle next to the Unternberg saddle (K?). The Unternberg summit and Unternberg Alm remain behind to your left. Now you follow the hiking trail via Simandlmais-Alm to the Brander-Alm (bew.). Climb the pasture to the forest and take a left on the bifurcation in the forest to the Ostertal and the meadow just below the Hörndlwand summit (K). Keep on straight and then bear right to soon descend steeply and difficult NW to the beginning of the Wappbach valley. On the bottom keep right (N) on good forestry road to aid station. Then, after the Röthelmoos Alm (V,K,bew.) take the second forestry road left in direction Jochbergalm. Take a forestry road left at 1085 m elevation and take another left onto a trail in a right hand bend at 1178 m elevation, leading to the Jochberg-Alm (K,bew.). From here continue on trail up to the saddle between Hochsattel and Mansurfer descend the other side to the Grundbach-Alm. Continue on rocky road to the Bischofsfelln-Alm (bew.) and follow N on difficult trail down to a forestry road, leaving the Hinteralm aside to your left to reach the Eschelmoos plain (K,↓66). You will pass very near this point again on k 85 coming from the oposite direction. But for now go left and descend down to the Kohlstatt parking area(A,K,V). Here you climb steeply, first on the ski slope to the second forestry road. It leads to the Gleichenberg-Alm (bew.). Keep right and follow narrow path to the Mittelstation (halfway station) of the Hochfelln cable car. Follow the hiking path and continue on forestry road level until a little ways before the Hocherbalm (K) where you make left onto a trail down through the forest onto another forestry road which leads you right to Maria Eck (bew.). Follow the road past the horse stables and then turn right to the aid station (V,A,K). Continue turning right to the Disselbachstube and follow the forestry road, then a trail about level leading towards Ruhpolding Obergschwendt (A) and on a road to Egg (A),(K,V↓80), which must be left before 18:15 if you want to continue on the 100k loop. Until 20:00 you can go for the 80 k shortcut-option from here. The 100 k course follows a hiking trail above the Farnböden-Alm, and to the last big climb to the Hochfelln summit (K, bew.). From the church on the summit turn S through fir bushes steeply and very difficult down and over to the Thorau saddle (1450 m) where you turn W and go down steeply (Caution! Roots, steep precipice to the Weissgraben). Eventually you cross the Weissgraben wash and reach a forestry road which you follow S down to the Eschelmoos-Alm (V,K) and continue on an easy slope down until you can take a forestry road left up, passing to the N of Gründberg and eventually leading unpleasantly steep down to Gruttau (A). Now follow pleasantly rolling forestry roads, trails and backroads to the left of the Urschlauer Aachen creek via Brand (K,bew.) to the Ruhpolding village limits (A). Here in Mühlwinkel you cross the creek and take the backroads to Wasen, Schwaig, Grashof finishing along the Traun river trail to the stadium (A,V,K).
