The Course des Châteaux d'Ottrott is a series of road races held in Ottrott, a village in Bas-Rhin, France's Grand Est region, each October. The event offers multiple race distances, including 5 km, 10 km, and a 21.741 km half-marathon, with children's races accompanying the adult events. It has been held annually since 1990 and is designed for families and recreational runners, not exclusively for competitive club athletes.
The race's name reflects its course, which leads participants toward the castles of Lutzelbourg and Rathsamhausen. Ottrott is situated in Alsace along an ancient Roman road leading to Mont Sainte-Odile, giving the race a connection to local history that is straightforward to appreciate. The organizers playfully note that "Ottrott" sounds like a horse trotting, aligning with the character of a community event that provides various options suitable for different ages and skill levels.
