Volunteers

About 21,000 Swiss sports clubs with their approximately 1.6 million active members provide a diverse and wide range of all kinds of sports. To make this possible about 350,000 people volunteer, what corresponds to an annual value of about two billions Swiss francs. As a result, they make an important contribution to the commonweal.
The Challengers Baseball and Softball Club thanks its volunteers for their dedication to the club, to the sport.
