About This Race

The 109K distance strikes a compelling balance for experienced ultra runners seeking a substantial challenge without the extreme demands of the 156K flagship. This route provides nearly 70% of the full ultra experience while maintaining more manageable cutoff pressures, making it an ideal choice for runners stepping up from shorter UTMB World Series events or those prioritizing strong finish times over maximum distance. The course allows runners to experience the full character of Alsace's varied terrain and cultural landmarks while still having energy reserves to appreciate the region's distinctive castles and vineyard passages in the latter stages.

Notable Features

The race takes runners through a landscape rich with castles and vineyards, offering a distinctive cultural trail running experience in the historic Alsace region. As part of the UTMB World Series, finishers earn Running Stones that count toward qualification for the flagship UTMB races in Chamonix, making this both a destination race and a stepping stone in the global ultra-trail community.
