Semi-Marathon de Rambouillet 2027

The Semi-Marathon de Rambouillet is a half marathon held in March in Rambouillet, west of Paris, organized by the Rambouillet Olympique club. It functions as a competitive road race and a local club event, supporting the Yvelines Departmental Championship and qualifying for the French Half Marathon Championships. The course defines the race: approximately one third runs through town, and two thirds crosses the Rambouillet forest. Participants go through the town center before moving to roads and cycle paths within the forest, transitioning from urban streets to extended wooded paths. Now in its 38th edition, it is an established spring event for half marathon runners in the Yvelines region.
