Les Dix des Ducs is a road race series in Montluçon, centered on a 10 km event. It begins at 11:10 from Quai Rouget de Lisle on rue Fargin Fayolle and concludes at place Piquand, beneath the Château des Ducs de Bourbon. This main race follows a two-loop course, recognized with an FFA Bronze label, and qualifies participants for the French 10 km Championship. Competitors must be born in 2010 or earlier and present an FFA license or a medical certificate for competitive running.
The course crosses the flatter sections of Montluçon, incorporating the suburbs, the Cher riverbanks, and the area near the ducal castle, avoiding a hilly, scenic route. Pace setters are available for 40, 45, 50, 55, and 60-minute finishes, catering to runners aiming for specific times and local club members. The 10 km race has a 1 hour 30 minute time limit, with the first loop requiring completion within 50 minutes. Montluçon Athlétisme also organizes shorter races of 5 km, 2.5 km, and 1000 m for younger participants, and entry numbers are capped by the organizer to ensure manageable race-day conditions.
