This weeks is 'Walk to School Week' and millions of children across the country are taking part in events to get kids walking to school.
Lots of mums and dads are worried about busy roads and because of this, more kids than ever are now being driven to school.
The government have set a target of getting 55% of primary school children walking to school by 2025.
But the charity Living Streets say they want the government to invest more into making this happen and help make roads safer.
They believe that walking to school is an easy and cheap way to increase exercise and make kids more healthy.
