The GutsMuths-Rennsteiglauf is Europe’s classic forest marathon festival, and the 2026 edition on 9 May once again turns the Thuringian Forest into a moving stream of runners, hikers and Nordic walkers. Distances span the full spectrum: the LOTTO Thüringen Supermarathon (~73.9 km from Eisenach), the marathon (42.2 km from Neuhaus am Rennweg), the hugely popular half marathon (~21.1 km from Oberhof), plus shorter formats such as the 10.7 km quarter marathon, 17 km hike, marathon hike and Nordic walking tours. All routes follow or intersect the historic Rennsteig ridge trail, with long forest sections, soft dirt paths, rolling climbs and descents, and big cumulative elevation gain, especially on the ultra and marathon courses. Famous for its rustic aid stations (broth, beer, goulash, cakes) and Volksfest atmosphere in Schmiedefeld am Rennsteig, the event mixes hard endurance with folk festival charm, making it a true bucket-list race weekend.
Races
On 9 May 2026, the LOTTO Thüringen Supermarathon leads runners over 73.9 km from the Marktplatz in Eisenach to Schmiedefeld am Rennsteig, organised by the GutsMuths-Rennsteiglaufverein e.V.. Following the historic Rennsteig trail through the Thüringer Wald with more than 1,800 m of ascent, this legendary point-to-point ultra is the cult classic that defines the event.
The INTERSPORT Marathon starts on Saturday, 9 May 2026 in Neuhaus am Rennweg and finishes, like all main races, in Schmiedefeld am Rennsteig, under the organisation of the GutsMuths-Rennsteiglaufverein. Covering about 42.2 km of forest paths, rolling climbs and descents along the Rennsteig, it’s one of Europe’s most iconic cross-country marathons.
Also on 9 May 2026, the TEAG Halbmarathon sets off from the LOTTO Thüringen ARENA am Rennsteig in Oberhof and heads 21.2 km to Schmiedefeld, organised by the same Rennsteiglaufverein.
