The Pas-de-Calais Urban Trail is a 10 km night urban trail held in Saint-Omer, Pas-de-Calais, Hauts-de-France. It takes place around mid-December, with participants starting after dark instead of following a typical daytime road-race schedule.
The course incorporates the city's public parks, historic cobblestone streets, and illuminated avenues, offering more variation than a simple flat loop. The event emphasizes its local character with the slogan “Pas de palais, Pas-de-Calais!”, appealing to runners seeking a brief winter challenge that includes urban exploration.
