The Corrida de Noël de Mainvilliers begins at the town hall in Mainvilliers, Eure-et-Loir, with the main race starting at 7:30 p.m. near Christmas. The adult race is a short city-centre night run of approximately 7.5 to 8 km, costing 9 euros, or 7 euros for FFA members.
The adult course consists of three loops, meaning runners pass through the same central streets multiple times; a headlamp is recommended for the 8 km race. Children have separate races, including one loop for benjamins and minimes and a half-loop Mini Corrida. Bib pickup is available at Ecole Emile-Zola from 5 p.m., and all participants receive a Christmas hat. Finisher numbers have increased from around 200 to over 600 in recent years, attracting a considerable local audience within a compact town-centre setting.
