Bolt Through 200m

Usain Bolt's coach Glen Mills says the Jamaican sprinter will not stop his pre-race antics despite his false start in the World Championships 100m final.

Bolt, disqualified from the final in Daegu, was criticised for the way he behaved prior to the race amid suggestions it showed a lack of focus.

But as Bolt prepares for his 200m defence, his coach says the Olympic champion will continue to be a showman.

"That is the heart and soul of the man and he will not change," said Mills.

"He will do the same. It is not something that is a cosmetic thing."

Bolt, the 100m and 200m world record holder, gets a chance to make amends for his error as he looks to defend his 200m world title with the heats getting under way on Friday.

Bolt out before Blake takes gold

The 25-year-old Jamaican is famed for entertaining the crowd with his antics before his races, including gesticulating to the camera, but some critics believe he may not have been sufficiently focused before Sunday's race.

However, Mills dismissed this as rubbish.

"That's his thing, it works for him. There is no perfect system. I don't think the false start had anything to do with his pre-race celebration. You could go into a race stone-faced and still false start."

Bolt himself has vowed not to dwell on the error, and Mills says his man is desperate to make amends.

"It shows you the passion of the man. He takes his competition very seriously," he added.

"He felt he not only let down himself but the millions of fans all over the world who were glued to their television expecting to see his performance.

"In time, he will be able to make up and repair that image."

Loughnane Suffers in Daegu Heat

The heat and humidity on the Daegu streets took its toll on Olive Loughnane in the early hours of this morning as the Galway athlete could only manage 16th place in the 20km walk at the World Championships.

A silver medalist in Berlin two years ago, Loughnane was some way off the podium today as the conditions made for a grueling challenge. The Loughrea athlete was dropped from the leading pack when eventual winner Olga Kaniskina upped the pace early in the race.

Although she managed to work her way back to the leading pack, subsequent lifts in pace saw her move further down the field to 23rd place at halfway point, over 23 seconds adrift from the leader. She crossed the line in 18th position four minutes adrift from Kaniskina, who successfully retained her title in a time of 1:29:42.

Kaniskina grimaced her way through downtown Daegu to win the title for a record third time. China's Liu Hong took the silver medal ahead of another Russian, Anisya Kirdyapkina, in third.

Kaniskina, who eclipsed compatriot Olimpiada Ivanova's mark with her third title, crossed the eight seconds ahead of Liu. World record holder Vera Sokolova had looked strong at the head of the field but at the hour mark started to suffer and dropped back to finish in 12th place.

With her tortured face slowly relaxing into relief, Kaniskina thrust her arms into the air to celebrate a third consecutive title as her weary legs dragged her over the line.

The walk was the only action on day five of the championships.

Pistorius Misses Out on Final

South African Oscar Pistorius' historic appearance at the World Championships came to an end as he failed to qualify for the 400m final.

The first amputee athlete to race in the competition finished last in his semi-final, clocking 45.39 seconds.

"My biggest goal here was to try and make the semi-final which I was able to do," Pistorius told BBC Radio 5 live.

"To have made the final would have been not impossible but it would have taken a miracle."

Olympic and world champion LaShawn Merritt of the United States eased into the 400m final as the fastest qualifier.

Britain's Martyn Rooney failed to make the final after finishing seventh in his semi in 46.09.

Pistorius, a four-time Paralympic champion, got a resounding reception from the 40,000 fans at the Daegu Stadium when he stepped up to the blocks in the third semi-final.

The 24-year-old made his usual slow start, but this time he never recovered, crossing the line last in a time 0.80 secs slower than his heat.

He added: "I think I'm a big realist in the sense that I knew the guys in my race were quicker than me.

"It's been a wonderful opportunity. [It was] not as quick as I wanted to be but it's great to have this platform to run on and it's been an unbelievable experience. I'll be back for the relay."

Pistorius will be allowed to compete in the 4x400m relay - with the heats set to take place on Thursday - providing he runs the opening leg to avoid endangering other athletes with the prosthetics.

Asked whether he could potentially compete at both the Olympics and Paralympics in 2012, Pistorius said: "Yes, most definitely. I've already run one qualification time. I've got to do another between January and June next year but I feel that's very much in reach. I've just got to keep doing what I'm doing."

A congenital condition meant Pistorius was born without fibulae - lower leg bones - and led to the decision to amputate both legs below the knee when he was 11 months old.

As a schoolboy, he preferred rugby union, water polo and tennis but took up running seriously in 2004 after it was suggested as part of his rehabilitation from a rugby injury.

He runs with carbon fibre prosthetic blades in place of his lower legs and was initially banned from competing in able-bodied events by the International Association of Athletics Federation (IAAF).

However, the Court of Arbitration for Sport (Cas) overturned the decision in 2008, paving the way for the South African to compete.

In July, the 'Blade Runner' clocked a personal best time of 45.07 in Italy to qualify for the World Championships just inside the cut-off time.

Powell Ruled out Daegu World's

Jamaica's Asafa Powell has been ruled out of the individual 100 metres at the World Championships in Daegu with a groin injury, but hopes to run in the relay.

The 28-year-old sprinter, fastest man in the world this year, had been expected to be one of the main challengers to defending champion and compatriot Usain Bolt at the event in South Korea.

But he will not line up when the heats get under way on Saturday due to the injury - the same problem which forced his withdrawal from the Aviva London Grand Prix at Crystal Palace earlier this month.

A statement from agent Paul Doyle read: 'Asafa Powell has officially withdrawn from the 100m event in Daegu citing a continued groin strain. Powell suffered a groin strain in Budapest on July 30 and has had recurring tightness and pain ever since.

'After Budapest, Asafa missed eight days of training before he could attempt to sprint again. When he returned to the track he was able to sprint but it caused the groin to flare up.

'He has received all sorts of treatments over the past two weeks in the hope of being prepared to run the 100m here in Daegu but today Asafa made the final decision not to run. He feels he would not be at 100 per cent and may have trouble coming back after each round.

'Asafa is very disappointed to say the least. He was really hoping to be able to run in what was going to be one of the most anticipated races of the championships. He is still optimistic to be able to run the relay.'

Amid confusing scenes at a Jamaican team press conference, it was fellow sprinter Michael Frater who appeared to let the cat out of the bag. 

While most reporters waited to speak to Bolt, Frater answered a question about his prospects by saying: 

'I didn't come here expecting to run the 100m but unfortunately Asafa couldn't make it.'

Jamaica team leader Grace Jackson then refused to answer definitely if Powell would compete, while Bolt also claimed to be in the dark when he eventually appeared on stage, adding: 'Asafa's out? That's the first I heard of it.'

Before pulling out of the meeting at Crystal Palace, Powell had spoken about his determination to claim a first global title. The 28-year-old said: 'I've learned not to get too comfortable, not to think that the medals are in the bag because I have a fast time. I have to work there and get it. 

'I try now to think of big races as just another race. It's not easy because we are all human and it's hard at a world championship final.'
