It aims to get more students walking and riding to school and encourages healthy lifestyles by increasing their physical activity.

Sunbury Heights teacher Emma Hyland said she hoped to see nearly three-quarters of students riding bikes or scooters to school.

Last year a little more than half rode. Out of 418 students, only 50 ride, walk or use scooters to get to school each day.

Bicycle Victoria's CEO Harry Barber said National Ride2School Day was a huge success last year with more than 1000 schools registering and 100,000 students enrolled.

"National Ride2School Day allows parents and teachers to embrace active travel as an alternative. The event has become the largest ever national celebration of walking and riding to school."

Ride2School events manager Mary Akiki said schools registered in the program had reported nearly half of their students were getting to school by riding, walking or by scooter.

"By actively getting to and from school, students' daily physical activity increases significantly, which benefits their overall health and helps reduce the risk of obesity and associated health problems."

National Ride2School Day is on Wednesday, March 17.
