Challenge Carrington is a long-standing cross-country race held in Louviers, Eure, Normandy. It takes place in late autumn and is a significant fixture on the French cross-country calendar, with this year marking its 86th running. The race is designed for endurance runners and competitive club athletes, not as a city road race.
Its primary historical distinction is being recognized locally as the dean of French cross-country races, signifying it as the oldest of its type in France. Recent events have attracted over 1,600 participants, demonstrating that it is more than just a heritage event; it continues to draw a large field to Louviers for a competitive day of racing.
