About This Race

The 18K strikes an ideal balance for runners seeking their first taste of technical Alsatian terrain without committing to ultra distances. This distance allows participants to experience the region's demanding climbs and descents at a manageable pace, making it perfect for trail runners transitioning from road racing or those looking to build confidence on more challenging terrain. Runners can fully appreciate the historical landmarks and vineyard passages without the time pressure that defines the longer ultra distances, creating an accessible entry point into the UTMB World Series experience.

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.
