The Kids Fitness Challenge is a free program offered to Massachusetts elementary and middle schools. The program aims to raise awareness about the lack of physical activity among school aged children, and the importance of physical education in schools. The fitness program seeks to have all students in each school which signs up participate in 30 minutes of constant activity in a creative way.

Each school that signs up to participate can hold their fitness challenge on any day of the scheduled week. The activity is determined by each individual school. All participating schools which reports 100% participation from their students in their 30 minute activity will automatically be entered in a drawing to receive one of four $500 grants to the school's physical education or health department, courtesy of the Bay State Games.
