The Les Crêtes Vosgiennes race challenges runners on the Rothenbachkopf and Rainkopf within the Parc naturel régional des Ballons des Vosges. The course includes technical descents near Lac Vert, with views over the Vosges and Alsace plain from the GR5 and Lac d'Altenweiher. This race, held since 1976, features a tradition of local Vosgienne cows cheering participants as they cross the blue line of the Vosges.
