The City Run des 1000 Marches is a 12.7 km urban trail race in Plombières-les-Bains, a spa town in eastern France. Runners begin at 7 allée Eugène Delacroix, at the end of the Casino parking lot, and encounter approximately 425 to 459 metres of elevation gain. It is organized by Association Sportive La Jeanne d'Arc de Plombières-les-Bains, with online registration and a GPX course file provided.
The race commences with 5 km in the forest, gaining 165 metres before transitioning to a semi-urban section through Plombières-les-Bains. The main challenge is the ascent of 974 steps, accounting for the "1000 marches" name despite the precise count being slightly lower. The event is connected to the Marche des 1000 Marches, and local historical accounts describe both as a means to highlight the town’s architecture, blending contemporary sport with regional heritage. The top three women and top three men receive prizes crafted as unique artworks by local artisans.
