“I came here to represent my country and I got the victory,” said Harrison, the world indoor champion who did not qualify for the Rio Olympic Games and only finished fourth at last year's World Championships.

“That's all I can ask for. 

"I am really blessed to come out here, be healthy and have fun with it.”
