The OstroVit Night Run takes place in Zambrów, offering 5 km and 10 km distances on a fast, flat city-street course. Known in Polish as the OstroVit Course Nocturne, it appeals to runners who prefer running after dark over early morning starts.
The course winds through Zambrów’s illuminated streets, with the streetlights contributing to the race atmosphere. Upon finishing, participants can visit the city center for a photo at the bison monument; the bison is a significant local symbol of Zambrów.
