Bolt would become the first man in history to win three straight Olympic Games 100m/200m double. He first tasted historic glory in Beijing 2008, when he ran 9.69 and 19.30, both world records at the time. He lowered both times to 9.58 and 19.19 at the World Championships in 2009.
He defended both titles in London 2012.
However, because of the super star’s limited outings this season, James believes based on history, he cannot bet against a proven performer.
“I think Bolt will win both events,” said James of the man, who shocked many doubters last year to win the World Championships 100m title.
Bolt had only three 100m races going into the 2015 Beijing World Championships, but dismissed American, Justin Gatlin, to take the title.
“He (Bolt) is a championship performer, I think that’s what he lives for, he loves the crowd, loves the stage, so I have him as the favourite for both events,” added James, who won the London 2012 400m title.
