Andy Turner turning up the heat as he sets sights on a hat-trick

Andy Turner believes he can break his personal best for the third time this year in the London Grand Prix tomorrow.

Britain's European and Commonwealth 110m hurdles champion ran 13.22sec at last month's Diamond League meeting in Switzerland, beating his previous best by 0.06 seconds, achieved in Jamaica in May.

At Crystal Palace, Turner will be lining up against USA's David Oliver and Dayron Robles, of Cuba, both of whom boast personal bests of under 12.90, as he looks to lay down a marker ahead of the World Championships in Daegu later this month.

Turner is not surprised by his improvement as he has been remodelling his technique with the aim of peaking for London 2012.

"It's still a work in process," said the 30-year-old. "This is almost a transitional year. I'm running consistently faster than I was last year and I don't think I've put a whole race together.
My personal best is only going to be temporary. Whether a faster time comes tomorrow, or in Daegu, I can't say but I'm sure it's coming soon."
