Hundreds of schoolchildren discovered the fun of running in Sheffield as part of a national campaign.
About 400 children took part in the Ineos Go Run For Fun event at Manor Fields Park, City Road, Manor.
The pupils were cheered on by British Olympic 3,000 metre steeplechase athlete Eilish McColgan as they completed a one-mile run around the park.
Pupils from Wybourn Primary School, Wybourn’s Emmaus Primary School, Phillimore Primary School in Darnall, Norfolk Park School, Manor Lodge Primary School, Manor’s Pipworth Primary School and Arbourthorne Community Primary School all took part.
They were led through a lively warm up and cool down before they got to ask questions of Eilish and her career.
Eilish, aged 23, who is looking forward to the Commonwealth Games in Glasgow later this year, said she took part in similar events was she was younger.
She said: “It’s a fantastic event to put on to encourage kids to try and keep fit and healthy.”
According to Public Health England, more than 50 per cent of primary schoolchildren are not getting enough exercise and 30 per cent of youngsters aged two to 15 are overweight or obese.
Craig Malkin, school sport co-ordinator for Links School Sport Partnership, said: “The main thing is to get them active and get them doing as much exercise as possible and celebrating a great event.
“We want children as active as possible, enjoying the outdoors and appreciating the outdoors in their local area.”
Ineos, one of the UK’s largest manufacturing companies, will invest £1.5 million over the next three years to establish a new charitable foundation to encourage children to run for fun.
It expects to hold 250 events over the next three years involving more than 100,000 children across the country.
Jim Ratcliffe, owner of Ineos, said: “I’m passionate about getting as many children running as possible as early as possible.
“The idea is simple – to get children out of the house having fun. It is not rocket science.
“Running is the basis of so many great sports. If our children can catch the running bug early, they’re more likely to stick to it, and this can only lead to them having more active and healthier lifestyles in the future.”
