About This Race
The Trail Alsace by UTMB 18K offers runners a focused introduction to the Alsatian vineyard trails that define this corner of northeastern France. Part of the UTMB World Series, the race starts from the medieval town of Obernai, where half-timbered houses and cobblestone streets give way to wooded paths and vine-covered hillsides. At 18 kilometers, this distance provides enough challenge to feel accomplished without requiring the multi-hour commitment of the event's longer formats. The course navigates the lower slopes of the Vosges Mountains, where the terrain shifts between smooth vineyard paths and more technical forested sections. Runners pass through small wine villages that have anchored this landscape for centuries, with the route designed to showcase both the natural beauty and cultural heritage of the Alsace region. The mixed terrain requires basic technical skills but remains accessible to runners stepping up from road racing or looking to build experience before tackling more demanding mountain courses.
Starting in Obernai, the route heads into the vineyards that blanket the eastern slopes of the Vosges. The course follows a mixture of wide vineyard tracks and narrower forest trails, with the terrain varying throughout. Runners should expect both runnable sections through the vines and more technical passages where roots and rocks require attention. The route returns to Obernai after a tour through the surrounding countryside, finishing in the town center where UTMB World Series events traditionally create a festival atmosphere.
