The GutsMuths Rennsteiglauf 2026 turns the legendary Rennsteig trail in the Thuringian Forest into a one-day carnival of running, hiking and Nordic walking. Its flagship is the LOTTO Thüringen Supermarathon (73.9 km) from Eisenach to Schmiedefeld, a tough ultra with nearly 1,900 m of climbing that has earned a reputation as one of Europe’s classic trail challenges. Alongside it, athletes can tackle the INTERSPORT Marathon (42.26 km) from Neuhaus am Rennweg, the TEAG Half Marathon (21.4 km) from Oberhof, or opt for the Nordic Walking half, Köstritzer 17.6 km hike, ¼ Wandermarathon (~10.5 km) and the youth-focused JuniorCross races. All courses share the same spirit: rolling forest singletrack and wide woodland paths, rustic aid stations, and a mass finish into Schmiedefeld am Rennsteig, where thousands of participants and spectators create a village-wide party. Steeped in East-German running history and known as “Europe’s largest cross-country run,” the Rennsteiglauf blends endurance, landscape and tradition like few other events.
