Going into the Games, 22-year-old Clarke’s aim was to reach the semi-final stage, as he looked upon the event as a chance of gaining experience for Rio in four years time.
But a personal best 13.31 seconds in the semi-finals qualified him for a shot at a medal as a fastest loser.
He actually ran a slower time in the final, clocking 13.39 seconds, but managed fourth place behind the American one-two of Aries Merritt and Jason Richardson, and Jamaica’s Hansle Parchment, who claimed bronze.
“When I came out to the track there was the most unbelievable noise, the crowd was absolutely insane,” said Clarke.
“I was out in lane two and I remember looking to the right and seeing all of the best hurdlers there has ever been, all of my idols and heroes and thinking what am I doing here?
“I just felt like I was totally out of place until I thought, do as well as you can.
“I can’t believe I finished fourth, I really can’t.
“I clashed arms with the guy next to me which was a bit of a disappointment because I feel like I could have run a personal best.
“But to come fourth in the Olympic Games is very surreal.”
