It was a case of on your marks, set and go for pupils at St Edmunds Community Foundation School.
Youngsters from the North Lynn school were in running action on Friday when they held a special event to raise money for child victims of the Nepal earthquake disasters.
All the pupils from nursery up to Year 6 took part by running, or walking laps of the school field.
Each circuit was counted and the challenge was to see how many marathons (26.2 miles) the school could achieve overall.
The school held a similar marathon challenge last year when it raised £850 for the Help Harry to Help Others cancer charity.
St Edmunds has become a keen provider of after school clubs over the last few years and the running club has been particularly popular and successful, a school spokesman said.
Forty-four children from the school took part in the Mini GEAR run in King’s Lynn earlier this month and all the pupils were full of enthusiasm when they were presented with a challenge such as raising money for charity, the spokesman added.
Parents were invited to take part in the fundraising as well by either walking or running. Parents and staff also held a cake stall.
The money raised will go to the quake victims through Save the Children Fund.
