Przełajowa Szóstka po Zmroku is a night cross-country run held in the Municipal Park of Tarnowskie Góry, Silesia. The primary race covers approximately 6.7 km, often stated as 7 km, designed for evening running rather than a typical road race. Participation is free, with a limit of 150 runners.
The start and finish are located at the park’s concert shell. The main race features electronic timing and age-group awards, suitable for runners seeking a timed result over a short off-road course. Shorter races for children are also part of the event, organized by the Szlifierka Association.
