Olympic sprinters James Dasaolu and Emily Diamond joined more than 500 youngsters to launch the Marathon Kids programme at Newham Leisure Centre.
The scheme, a partnership between Nike and charity Kids Run Free, aims to provide fun running experiences for children.
James, who took up running seriously after London 2012 said: “Running is uniquely accessible – all you need is a pair of trainers to get started and it doesn’t have to be on an athletics track; it can be at your local park or around your local area.”
