If school is a child's "workplace," the daily trip to school is the child's "commute." This trip may be taken in a car or bus, but if it is taken on foot or by bicycle, it offers children multiple opportunities for regular physical activity--a vitally important benefit at a time when overweight and related disorders are increasingly common. This article discusses the health benefits of bicycling or walking to school, as well as the ways in which children can be encouraged to use walking and bicycling as safe and preferred modes of transportation.
