The controversy surrounding Olga Yegorova's participation at these championships ended with a twist when she won the gold medal in the women's 5000m.

The Russian was booed by the crowd as she completed the race and decided not to do a lap of honour as is traditional.

Yegorova, who tested positive for the banned blood booster EPO last month, was allowed to compete after it was revealed only a urine test had been taken and not blood as IAAF rules require.

At a tense press conference following the race, in which she saw off the field with a devastating final 250m, Yegorova was grilled by reporters over the issue.

She said she 'forgot' to run a victory lap and about the crowd's response she replied: "Maybe it's their personal business and their personal choice, but I do not consider myself guilty.

"It's up to them, it's their business."

The 29-year-old still has to collect her medal at a victory ceremony on Sunday.

Regarding that public outing, she said: "I don't know how the fans will react to the awards ceremony tomorrow, but what do you think?

"Should I have come second or third to please the fans?"

Yegorova, who put her failed test down to 'a mistake' also condemned those who used EPO, which creates more red blood cells which carry oxygen around the body, saying: "Of course I condemn them because it's not good for their health."

She said the improvement to her performances in the last two years had been due to changes in her training.

"I did change my training a little bit. I did some training at altitude which is something I'd never done before and also increased the total mileage a bit."

She also explained that as she had been a 1500m before turning her attentions to the 5000m, it had taken a while for her to learn the event.

Yegorova's sprint finish pushed Spain's Marta Dominguez into the silver medal position, more than three seconds back, while Ethiopian Ayelech Worku took bronze.

Dominguez said she felt the press had gone 'too far' in their questioning of Yegorova.

When asked if she felt she was the real champion, Dominguez replied: "No. For me I came second.

"It's quite clear for me that the winner is Yegorova. I'm happy until anything is proven otherwise."

Britain's Jo Pavey, who finished 11th in the race, said it was the 'worst possible result, her actually winning the race'.

"All we can hope for is for us to open the gates for a level playing field."
