Speaking to The Observer, Sierra Leone's top male runner Idrissa Kargbo said: "I don't know if she will come or not. If she comes, it's good for her career. If she doesn't, her career is over. She will have to forget about running."

Since the race it has emerged that Lahun deliberately ran away but is safe and well, although her whereabouts are not known.
