Up the mountain. The alternative to the 44 km long Koasa Marathon. A real half-marathon mountain run with a beautiful route through the Kaisergebirge nature reserve. The Musikantensteig takes you from Ebbs to the Vorderkaiserfeldenhütte. Almost 1.000 hm on the first 5,2 km! From there with a constantly excellent view down. Also a highlight for hikers.
