At twenty years of age, Luke Morton from Nottinghamshire seemed to be fit and healthy. But in February this year, he died - a victim of Sudden Adult Death Syndrome. Now, his mother wants to pay a special tribute to him.
This Sunday, Suzanne Morton will become one of the first people to run at the Olympic Stadium in London since the games ended. She'll join hundreds of other charity runners as Olympic Park is officially re-opened. And as Gareth Owen reports, it's a place with a special meaning for Luke's family.
