After the fall break, indoor practices will begin for the Challengers teams and thus preparations for the 2025 season. The gyms remain unchanged from last year, with pitcher/catcher practice in the Ruggächer sports hall in Zurich-Affoltern, baseball practice in the Probstei gym in Zurich-Schwamendingen, softball practice in the Gabler gym in Zurich-Enge and junior practices in the Auhof and Herzogenmühle gyms in Zurich-Schwamendingen.
