Derval O'Rourke has narrowly missed out on a medal at the World Athletics Championships in Berlin after finishing fourth in the final of the Women's 100 metre hurdles.

O'Rourke set an Irish record in an incredible performance with a time of 12.67seconds.

The Leevale athlete had a lightening start and was close to leading at half way before the rest of the field pulled her back but the 28-year-old had enough quality to push through in the last 50m and take fourth place in what was truly world class competition.

Earlier today O'Rourke finished fourth in her semi-final in a season's best time of 12.72 second to qualify for the final.

Running in lane one, O'Rourke made a typically quick start and led in the early stages before being overhauled by winner Brigitte Foster-Hylton of Jamaica, silver medallist Priscilla Lopes-Schliep of Canada and Delloreen Ennis-London of Jamaica.

'Fourth is a hard place to be but when I've finished fourth I've always built on it,' said O'Rourke, who was just 0.12secs behind Ennis-London.

'It's a national record. It took me three years to get back to this territory and I have to be incredibly happy and just have a tiny pity party, but outside of that I have to be very happy.

'Fourth at the worlds, if you had told me that last year at the Olympics (when she went out in the heats), I would have killed you for it.

'I knew I had to run my socks off to make the final and I didn't want to be the person who is the token lane in the final. I wanted to be there and represent myself really well and keep my head held high and do well.

'I think I'm as good as everybody in the world on my day and it's just frustrating.'

She added: 'I've had so many bad days so I can take this and smile.'
