Farah Misses Out on Medal

Britain's Mo Farah missed out on a medal in the 3,000m at the World Indoor Championships after briefly being upgraded to bronze.

Farah collided with Kenyan athlete Edwin Soi and went on to finish fourth in seven minutes 41.79 seconds.

He was awarded the bronze position after the race, only for that decision to be reversed on appeal.

Shara Proctor , Andrew Osagie and Holly Bleasdale won bronze medals in the long jump, 800m and pole vault respectively.

There was similar controversy in the men's 4x400m relay as the GB team of Conrad Williams , Nigel Levine , Michael Bingham and Richard Buck were promoted to a gold medal after the United States team were disqualified.

Farah, who finished ahead of Lagat in the 5,000m world outdoor final last August, had attempted to take the lead two laps from the end.

As Soi and fellow Kenyan Augustine Choge chased him, Soi collided with Farah in the final bend causing him to step off the track.

Farah said following the race: "I'm disappointed to finish fourth. I got pushed a bit but that's all part of the sport."

American Brittney Reese took the women's long jump crown with an incredible 7.23m on her final jump.

Proctor had equalled her British record of 6.86m in the third round before extending it by three centimetres to claim bronze behind Reese and Janay DeLoach.

The Anguillan-born athlete said: "Getting a bronze amongst all those great jumpers, I'm happy to wear this [British] vest. I'm feeling great, I can't ask for anything more."

There was a surprise medal for 24-year-oldOsagie, who took bronze in the 800m despite struggling with injury in recent months.

Bleasdale secured third place in the pole vault on her first major senior event with a best of 4.70m, behind Russia's two-time Olympic champion Elena Isinbaeva and Vanessa Boslak of France.

On a days which secured a record medal haul for Britain at a World Indoor Championships, the women's 4x400m relay team won a thrilling race just ahead of the United States.

Shana Cox , Nicola Sanders , Christine Ohuruogu and Perri Shakes-Drayton set a world-leading time of 3:28.76 to win one of three gold medals for GB at the Championships.

Winning nine medals in total, GB improved on their previous World Indoor record set in Birmingham in 2003.

In a hard-fought high jump competition with eight men all jumping over 2.31m, Robert Grabarz finished outside the medals in sixth with a best of 2.31m. Greece's Dimitrios Chondrokoukis lept to a personal best of 2.33m to win gold ahead of reigning Olympic champion Andrey Silnov of Russia.

Similarly, a strong women's 3,000m field kept Helen Clitheroe from the medals as she placed seventh in 8:59.04. Kenyan Hellen Obiri took the race in 8:37.16.

Andrew Pozzi capped an impressive debut World Indoor Championships by finishing fourth in the 60m hurdles. The 19-year-old, who ran personal-best times in the run-up to the final, clocked 7.58 as America's Aries Merritt claimed victory in 7.44. Xiang Liu of China and France's Pascal Martinot-Lagarde trailed.

Neither of Britain's young female sprinters were able to impress in the 60m, with Asha Philip and Jodie Williams both failing to qualify for the final.

Chambers Prepares for Real Race

Dwain Chambers ready for Court of Arbitration for Sport hearing

Dwain Chambers is prepared for the possibility that his London 2012 hopes will be ended by a Court of Arbitration for Sport hearing starting on Monday.

The 33-year-old is contesting a British Olympic Association by-law that excludes drugs cheats from selection.

"I've got my mind around the possibility of that happening," he said of the chance of his appeal failing.

"I have no idea what the outcome will be and that does make it difficult. It does bother me."

Chambers, who won bronze in the 60m in the world indoors championships in Turkey on Saturday, was banned for two years in 2003after being found guilty of taking anabolic steroid THG.

The World Anti-Doping Agency believes Chambers should be free to compete having served his suspension, while the BOA argues that its requirement for athletes to have clean drugs record is part of its selection criteria rather than an additional punishment.

BOA chairman Lord Moynihan has insisted Chambers and others who would become eligible would be welcomed back into contention for the London 2012 team if Cas rules against it.

Chambers, who has also been excluded from major domestic meetings on account of his positive test, says he has come to terms with his predicament and has been pleased by his Great Britain team-mates' reaction to him.

"I had to grow up. I had to review my situation and realise I was the culprit and the one making mistakes," he added.

"The athletes are very supportive. They support me and I support them. That's what's making it more enjoyable.

"If it goes our way, it would be fantastic. But I can't get too happy because I still have to qualify.

"Even though I'd become eligible, I'd still have to qualify. These youngsters are getting faster and I'm getting older, so it's becoming that much harder."

Chambers has received support from American sprinter Justin Gatlin who beat him to gold in Istanbul.

Former 100m Olympic champion Gatlin, who was banned for four years after testing for testosterone in April 2006, is free to compete in London 2012 as the United States team is open to athletes who have served drugs bans.

"He's one of the best runners in British history," said Gatlin.

"He came back after all his trials and tribulations and established himself as one of the best runners for the UK team.

"I think he has proven himself as a God-given talent and a good runner and to have him on that line in the Olympics would be a great show."

Ennis Second to Dobrynska

Britain's Jessica Ennis had to settle for silver as Olympic champion Nataliya Dobrynska of Ukraine won the pentathlon at the World Indoor Championships.

Ennis needed to beat Dobrynska by a sizeable margin in the closing 800m to retain her world indoor title.

The Briton thought she had done enough when official scoring suggested she had won when she crossed the line first.

“I'm absolutely gutted, it was a terrible long jump”Jessica Ennis

But her celebrations were quickly cut short when it was confirmed that Dobrynska had broken the world record.

The Ukrainian managed to finish within three seconds of Ennis - who ran a personal best - and set a new pentathlon world best of 5013 points, ahead of Ennis on 4965 points and Lithuanian Austra Skujyte on 4802.

"It's the worst feeling in the world," Ennis said of initially seeing her name in first place after the 800m. "I looked at the scoreboard and thought I'd won."

Ennis had begun the day in Istanbul with a brilliant run in the hurdles, dominating the field to win in 7.91s, but flirted with disaster in the high jump until clearing 1.87m at her third and final attempt.

The Sheffield athlete responded with a shot put of 14.79m - the furthest she has ever thrown, indoors or out - to lead by 10 points overall heading into the long jump.

But after an opening leap of 6.19m, Ennis followed up with 6.18m before being red-flagged for overstepping the board on her final effort.

"I'm absolutely gutted, it was a terrible long jump," she said, knowing that she had left herself a huge task in the 800m.

Russia's world heptathlon champion Tatyana Chernova had an even more disappointing day, finishing in fifth place behind Poland's Karolina Tyminska in fourth.

Elsewhere, reigning 60m champion Dwain Chambers progressed comfortably in the heats, as did fellow Briton Mo Farah in the 3,000m.

Chambers won his opening round in 6.64 seconds, matching the time of American Justin Gatlin in the previous race, and said: "It's nice to get the first heat out of the way."

Farah had to put in a sprint around the final bend of his heat with only the top four making the final, but in the end he came through in second place.

"I had to dig in hard," said the Londoner. "My aim was to slowly wind it up and try to get rid of as many people as possible. It's all about the final and trying to save as much energy as I can."

Britain had enjoyed an impressive start to day one, with Yamile Aldamamaking Saturday's triple jump final in the first round of qualifying with 14.62m - the third longest indoor jump of the year.

European indoor 3,000m champion Helen Clitheroe qualified for the 3,000m final as fastest loser in 9.02:27. She said: "It's always a massive relief to get through the heats, I'm pleased. I wanted to make sure I was in the first four or, if it was a fast time, get through as a fastest qualifier."

Nadine Okyere joins Shana Cox in Friday's 400m semi-final, while Joe Thomas and Andrew Osagie qualified for the 800m semi-final, both running 1.49:73.

In the men's 400m, Richard Buck (47.05s) and Nigel Levine (47.56s) will join world outdoor 400m champion Kirani James of Grenada in the semi-finals at 1810 GMT.

Australian 60m hurdles star Sally Pearson looked imperious as she won her heat in 7.41 seconds but Kristi Castlin, ranked number one in the world last year, went out in controversial circumstances.

The American was one of several athletes during the day to incorrectly think there had been a false start, with Jamaican sprinter Lerone Clarke another to make an early exit before complaining about the starter's gun.

Mo Farah Decides on Istanbul Indoor

Mo Farah will compete as part of the Aviva Great Britain & Northern Ireland team at next month's IAAF World Indoor Championships in Istanbul.

The reigning 5000 metres world champion revealed on Saturday that he and his coach Alberto Salazar had yet to decide whether he would take part in the 3,000m in Turkey after Farah lost in Birmingham over two miles at the weekend.

However, the 28-year-old has been included in the 39-man squad for the finale of the 2012 indoor season.

Defending world champion Jessica Ennis will look to retain her pentathlon crown with sprinter Dwain Chambers also hoping to defend his world indoor 60m title during the event which takes place between March 9-11.

Perri Shakes-Drayton, who won 400m hurdles bronze in 2008 but has not made an appearance this winter due to a hamstring injury, is named in the women's 4x400m relay squad.

British indoor record holder Holly Bleasdale will compete in the pole vault, while UK indoor long jump record holder Shara Proctor, 4x400m sepcialist Christine Ohuruogu, 60m hurdler Tiffany Porter and triple jumper Yamile Aldama are also part of the team that will travel to Turkey.

UKA Head Coach Charles van Commenee said: "This is a strong team and one that can realistically challenge for medals and make finals.

"There are some good athletes coming through and I am looking forward to seeing how they perform on the senior international stage.

"There have been some good performances during the indoor season which bodes well for Istanbul and beyond.

"The indoor season gives useful information about how athletes are progressing. It is important to remember the focus still remains on London 2012."
