About This Race
The 109K represents the most substantial challenge in the Trail Alsace Grand Est lineup, demanding advanced ultra-distance experience and sophisticated pacing strategies across the region's demanding terrain. This distance requires runners to master both the technical aspects of the Alsatian trails and the mental fortitude needed for extended time on course, making it ideal for seasoned ultrarunners seeking a serious test without committing to the full 156K distance. The extended effort allows runners to fully experience the transition from day into night across the historic landscapes, creating a more immersive journey through the region's medieval heritage.
