Nocna Zmiana is a night run in Polkowice, Lower Silesia, starting at 10 PM. The primary event is an individual 10 km race, with relay and team options available, including a 2 x 5 km relay and team categories for women, men, and mixed groups. The start and finish are located at the Picnic Center, ul. 3 Maja 50. The race office and bib collection are situated nearby at the Grzybek outdoor swimming pools.
The course follows a 5 km loop along ul. 3 Maja and Przemysłowa, incorporating a lap within the Athletics Stadium. Consequently, the 10 km race consists of two night loops, not a point-to-point format. The event originated as the first Polkowice Night Run, suggesting a local, developing race rather than one with a long-standing tradition. Results from an early edition indicate a predominantly Polish participant base, with runners hailing from Polkowice and surrounding Lower Silesian towns like Legnica, Lubin, Głogów, Jawor, and Przemków.
