The profiled route leads the participants via Hinterwinkel to the Zwölferhorn, at 1,500m the highest elevation of the competition.

The magnificent all-round view of Lake Wolfgang and the Salzburger Land rewards the effort of the ascent. Via St. Gilgen and along the shore of Lake Wolfgang, the runners can expect the second big climb up the Schafberg to the Schafbergalm after about 55km, before heading back towards Fuschl and along the north shore of Lake Fuschl. After 95km it’s time to mobilize your reserves again, because the second last climb up to the Nockstein up to 1,000m follows.

Once at the top, the fantastic view of the city of Salzburg will hopefully give the runners a last boost of motivation to tackle the final 10km over the Kapuzinerberg back to the old town of Salzburg with lots of energy, where they will be rewarded with an unforgettable finish and their hard-earned medal.
