The Bieg im. Braci Mikrutów, also known as the Koronowska Piątka, is a local road race held in Koronowo. The primary event is now a 5 km race, a change from the previous 10 km distance, and this adjustment includes a modified route. It takes place in September. The race's name honors the Mikrut brothers, lending it a local commemorative identity distinct from a generic city race.
Participants begin on ul. Wąskotorowa, proceeding through streets such as Dworcowa, Ogrodowa, Garncarska, Plac Zwycięstwa, Bydgoska, Klasztorna, Sienkiewicza, Paderewskiego, Pomianowskiego, and Witosa, before concluding by the sports hall, also on ul. Wąskotorowa. This marks the event's twelfth edition. The reduced distance positions it as a quick town 5K, differing from the former longer road race format. A Facebook photo gallery documenting the race is publicly available.
