American star targets Ohuruogu scalp

Sanya Richards-Ross expects 400 metres rival Christine Ohuruogu to once again rise to the occasion on the big stage at the London Olympics - but is determined the Briton will not get the better of her this time.

Having gone into the 400m final at the Beijing Games in 2008 as favourite, America's Richards-Ross had to settle for bronze as Ohuruogu followed up her world title by making off with the gold medal. It remains the only time the British athlete has triumphed in a race between the pair and Richards-Ross was subsequently crowned world champion a year later.

Asked if she regarded Ohuruogu as a threat in London, Richards-Ross told Press Association Sport: "Absolutely. The one thing about Christine which means we can't count her out is that when it comes to major championships, she shows up and runs really well."

She added: "I think if you look at our record, she has only beaten me one time, but it really doesn't matter because she won the one that I wanted the most, so I think that evens out the rivalry. I definitely consider it that and I am really hoping that I can beat her this time at the Olympic Games - that is what I have been training so hard for."

Richards-Ross was speaking in Manchester ahead of Sunday's Great CityGames there, where she will be competing in the 200m.

Among the British contingent taking part is Andy Turner, who is aiming to win both the 110m hurdles and 200m hurdles races for a third straight year and also has his sights firmly set on Olympic glory.

The 31-year-old won a bronze medal in the 110m event at last year's World Championship in Daegu but only after being promoted following the disqualification of Dayron Robles.

The experience left Turner with mixed emotions and he wants a "legitimate" place on the rostrum this summer.

"The thrill of winning a medal for me is not standing on the rostrum - it is the thrill of crossing the finishing line, knowing that you have come in the top three," Turner said.

"That is the feeling that I train for and I didn't get that in Daegu. To be promoted to third and just handed a medal kind of took away from everything, so this time definitely - I want to earn my place on the rostrum with a legitimate top-three finish."
