About This Race
The 109K serves as the flagship ultra distance in the Trail Alsace Grand Est by UTMB series, offering a substantial challenge through the diverse landscapes of France's northeastern borderlands. Starting from the medieval town of Obernai, runners traverse the distinctive mixed terrain of the Vosges foothills and Alsatian vineyards, navigating technical sections that demand careful footwork alongside more runnable passages. The course provides an authentic ultra experience that extends through daylight and into darkness, testing both physical endurance and navigational skills across a region steeped in Franco-German heritage. This distance attracts experienced ultrarunners seeking a serious challenge within the UTMB World Series framework. The 109-kilometer route requires well-developed pacing discipline and self-sufficiency between aid stations, though specific elevation data is not currently available. The extended time on course allows runners to experience the full character of the Alsatian countryside, from sun-drenched vineyard trails to nocturnal forest passages. As part of the UTMB World Series, this race offers qualifying points for runners building toward larger events in the circuit. The Obernai base provides cultural immersion beyond the race itself, with traditional Alsatian architecture and regional cuisine forming part of the weekend experience.
