Biegi Gąsawskie im. Gustawa Mądroszyka is a race event held in Gąsawa. It starts and finishes at the Leszek Biały Municipal Stadium on Sportowa Street. The primary race is the 10 km “Dziesiątka Gustawa.” Additionally, there is a 5 km Nordic Walking route and races for children and youth covering 800 m, 1200 m, and 2000 m. This series is a component of the Grand Prix Pałuk, integrating it into a broader local racing circuit.
The 10 km route combines asphalt and cross-country terrain, guided by a pilot. The course departs the stadium, proceeds through streets including Sportowa, Ogrodowa, Słoneczna, and Trzemeszeńska, and then heads towards Huby Gąsawskie and Komratowo. The Nordic Walking route is shorter, primarily on asphalt and cobblestone, also with a pilot. Medals and cups are awarded, and medical support is available.
