Human Machine 100 km
The Human Machine 100 km is an endurance race held in Piotrków Trybunalski, utilizing a straightforward 10 km loop. Completing the full distance requires 10 laps. Participants are not restricted to running; they may also walk or use Nordic walking poles. The course follows typical urban surfaces such as roads, sidewalks, and road shoulders, making the primary challenge sustained effort over multiple laps rather than technical difficulty. The race is limited to 200 participants and is organized by Stowarzyszenie HUMAN MACHINE. A distinct tradition is the absence of awarded places for first, second, or third; the objective is completing the chosen distance. Any shorter distances must still be completed in full 10 km increments, maintaining a clear and straightforward format. Adults may register independently, while younger participants require parental consent and supervision.
