About This Race

The 156K stands as the ultimate test at Trail Alsace Grand Est, demanding exceptional endurance as runners traverse the full breadth of the region's challenging terrain multiple times or across extended single-track sections. This distance requires experienced ultra-distance runners who can manage complex fueling strategies and maintain focus through potentially 20+ hours of continuous movement across varied elevation profiles. The extended time on course means experiencing the full cycle of weather conditions and lighting changes while navigating the technical demands that make shorter distances challenging, amplified across a much longer journey.

Notable Features

This UTMB World Series event uniquely combines trail running with cultural immersion, taking runners through Alsace's historic landscape of castles and vineyards. The themed race names honor the region's rich medieval heritage, while the courses showcase the distinctive Franco-German character of this border region. As part of the UTMB World Series, finishers earn Running Stones that count toward qualification for the prestigious UTMB Mont-Blanc.
