Czastarska Piątka is a 5 km street race held in Czastary, a village in central Poland, during the local Dni Czastar festival. The race office is located in the Primary School courtyard, giving the event a distinctly local character unlike a large city run. Participation is open to individuals aged 16 and above, with minors requiring written consent. The field is limited to 200 participants.
The course follows Szkolna and Słoneczna streets and passes through the adjacent village of Kniatowy. Competitors are ranked in overall and age categories, with additional classifications for Czastary municipality residents. All finishers receive a commemorative medal. Electronic timing is provided using returnable chips. The race was established in 2014 following an idea by Jarosław Urbaniak and Marek Dudka. Towarzystwo Przyjaciół Czastar organizes the event, with assistance from local government, cultural organizations, the fire service, and sports groups.
