La Chavaign'Hard - Montreuil-sur-Ille 2026

La Chavaign'Hard is a short, backyard-format running race held in Montreuil-sur-Ille, located in France's Ille-et-Vilaine department. It takes place near Christmas, with the primary date noted as the day after Christmas. The loop distance is specified as 6.7 km, often rounded to 7 km in race listings. The key aspect is its format: a backyard race requires participants to run the same loop repeatedly on a set schedule, unlike a point-to-point race. This event caters to both running and ultra-running enthusiasts, designed for those aiming to test their endurance over extended periods by returning to the start line, rather than completing a single 7 km run.
