More than 7,000 pupils from 43 primary schools in Gloucestershire have signed up to walk, jog or run a mile every day between now and the summer holidays.
It's all part of Active Gloucestershire's Daily Mile initiative which is being officially launched at Cheltenham Racecourse.
Our ambition is to improve children's health and wellbeing through regular activity and spending time in the fresh air every day. A short exercise break from curriculum can bring so many benefits to both pupils and teachers by helping children to be healthier, more productive and alert.
Children at Twyning School in Tewkesbury run every day, whether on the school playground or the village green for older pupils. They have been doing it for a year and teachers say it has far-reaching benefits.
The evidence is strong that their health improves, they do better in class. It can improve mental health and as we know there is a lot of evidence to show that children's mental health is getting worse as they spend more time in front of screens.
With childhood obesity rates rising, encouraging physical activity at an early age is important, and research has shown that children who are overweight in primary school are less likely to revert to a healthy weight in later life.
The Daily Mile is a great initiative, and I wholeheartedly encourage primary schools to participate.
What is clear is that the children enjoy their Daily Mile. Here's what Twyning School pupils think:
It is not too late to sign up to Active Gloucestershire's Daily Mile challenge.
