The Semi-marathon intercommunal de la vallée de l'Orne is a 21.1 km road race in Moselle, focused on Vitry-sur-Orne and the Orne valley. Runners begin at 9:30 AM in Clouange, with the event organized by SMIVO. It is a local half marathon offering changing rooms and aid stations on site, with a low entry fee.
The course connects six communes: Clouange, Rosselange, Moyeuvre-Grande, Rombas, Vitry-sur-Orne, and Gandrange. This intercommunal setup defines the race: rather than staying within a single town, the route uses the valley’s neighboring communities as its structure. The series has reached its 27th edition, marking it as an established event for runners in this part of the Grand Est region.
