Plywanie Grand Prix Puchar Polski na Wodach Otwartych Tarnowskie Gory

Swimmers begin at Zalew Nakło-Chechło for the Tarnowskie Góry stage of the Grand Prix Puchar Polski na Wodach Otwartych, an open-water swimming competition in Silesia, Poland. The event takes place in June, featuring a range of distances: 300 m, 500 m, 1 km, 3 km, 5 km, 7.5 km, and 10 km. The shorter distances accommodate novice open-water swimmers, while the 5 km, 7.5 km, and 10 km races provide a significant endurance challenge for seasoned athletes. MKS Park Wodny Tarnowskie Góry is the organizer, and the reservoir location ensures the competition centers on open lake swimming, distinct from a pool setting.
