Sutton's Andy Turner blamed a niggling hamstring injury for his poor performance in the British Grand Prix at Crystal Palace on Friday.

The 110m hurdler finished a disappointing sixth, having made a false start, in just 13.72 seconds, more than half a second behind winner David Oliver.

“It’s just another injury to add to my collection this year,” said the 27-year-old.

“I’ve been carrying a hamstring niggle since I raced in Lucerne last week. It’s like a nerve pain going into my hamstring and I’m having an epidural injection on Monday to hopefully get rid of that.

“At one point in the warm up I said to my coach I was going to have to scratch the race because it was so sore but when you get out there the adrenalin gets going and I didn’t feel it out there.

“I tore my other hamstring only about six weeks ago so it’s just been one thing after another. In January I tore a disk in my back, it’s just been constant.

“I’ve not had a block of solid training yet and it’s showing in my races and I’m hitting hurdles. I feel like I’m running probably my best flat speed but there is no point doing that if I’m not technically right over the hurdles and that’s what I’m lacking at the moment.”

Turner is flying out to the Team GB training camp in Macao later this week but admits his preparations have been hampered.

“It’s not the ideal preparation as I’ve not managed to train properly this week.

“Hopefully come Monday I’ll get this injection done and then move on and start proper training.

“If I can go to Macao injury free like I did at the world championships last year then I can go to the Olympics and produce my best like I did last year.

“If I had that time of good solid training I know I can run another personal best, I know I can.

“There’s a lot of guys out there running fantastic times. It just takes one big race for them guys to pull you along and to produce a big personal best. It’s exciting to race them boys.”
