A primary school in Harpenden is taking part in the country's biggest inter-school active travel challenge next month.

The Sustrans Big Walk and Wheel, which takes place from March 11 to 22, will see Roundwood Primary School pupils travel to school by walking, wheeling, scooting or cycling to improve air quality and learn how these changes benefit the world.

Mrs Hooft, the school headteacher, said: "Walking to school is an easy way to get the blood pumping and meet the physical activity requirements that scientists say will help children lead longer and healthier lives."

The challenge is open to all UK primary and secondary schools, and offers prizes everyday.

Etta, a member of Roundwood Primary’s Eco Council, said: "We plan to get the whole school involved.

"We are making posters to promote this week but our aim is that everyone walks, scoots, skates or rides to school every day."

The challenge has helped parents save £1.6million in petrol costs and teachers found pupils who walk, wheel, scoot or cycle to school arrive more relaxed, alert and ready to start the day.

Xavier Brice, chief executive officer of Sustrans, said: “It’s great to see Roundwood Primary taking part in the Sustrans Big Walk and Wheel this year.

"Parents save money by not having to drive and children get to be out and about exploring their world. This gives our children healthy habits they can take with them into adulthood.”
