15. Biegi Małego Fabrykanta

Bieg Fabrykanta is a street running event held in Łódź in late August, starting and finishing within the Łódź Special Economic Zone. The main race begins in the early evening, with a field limit of approximately 2,000 participants, positioning it as a significant running event in the region. The course crosses Księży Młyn, the historic factory district that aligns with the race's name and provides a distinct Łódź atmosphere. The event also features the Mały Fabrykant races for children, the Bieg Fabrykanta jest Kobietą 2.0 initiative to encourage women in running, and a charity Grohman Mile. Entry fees for the Grohman Mile are donated to the Łupkowa children’s hospice, with a matching contribution from the Łódź Special Economic Zone.
