Semi-Marathon intercommunal de la Vallée de l'Orne 2027

SMIVO, the Semi-Marathon intercommunal de la Vallée de l'Orne, is a 21 km trail race in Moselle, Grand Est, France, running between Metz and Longwy. Held around March, it covers the half-marathon distance, but its terrain and setting define it as a valley trail rather than a flat road race. The course connects towns in the Orne Valley, blending natural paths with urban segments. Recent starts have been in locations like Rombas and Clouange. As an established event in the local running calendar, its intercommunal nature is key to its identity: it focuses on crossing multiple communities instead of looping a single city center.
