With over 6,000 participants already signed up, and the three shorter distances sold out months ago, anticipation around the top-tier sporting experience that showcases the Alsatian landscapes is at an all-time high.
For the 2025 edition, organisers have introduced a fifth race format to make the event even more accessible: ‘La Ronde des Pages’. This shorter, semi-nocturnal route, starting in Obernai, is designed as an entry point for newcomers to trail-running, offering them a taste of adventure in an approachable format.

The race promises a spectacular and inclusive experience and is open to all runners aged 18 and above. Addditionally, as part of the 20K category, all finishers will earn 1 Running Stone.

Sébastien Spehler returns to defend his title on the new 100M course
