Paula Radcliffe blood data 'proves her innocence'

The 41-year-old insists the data was cleared by the IAAF and exonerate her of any wrongdoing.

In data seen by Sky News, Radcliffe claims that altitude training and the timing of the tests led to “off-scores” of 114.86, 109.86 and 109.3, with anything over 103 considered unusual for female athletes.

This "normal" threshold can go up because of a number of factors, including altitude training and tests taken immediately after extreme exertion.

The marathon world record holder says the highest of the three values came from a sample taken immediately after a half marathon in extreme heat in Portugal.

The World Anti-Doping Association now considers any samples taken within two hours of competition as invalid, because exertion can affect blood values.

Radcliffe says the test results were followed up and cleared by the IAAF at the time they were given, and she has since had independent expert advice that clears her name.

The three tests are taken from an IAAF database of athletes' blood samples leaked to the Sunday Times and German broadcaster ARD, with the newspaper claiming the results were "highly unusual" and "abnormal" and that one of the test results could be attributed “to an illicit blood transfusion, but this is only a suspicion and certainly not proven by the results".

Earlier on Thursday, Radcliffe spoke to the BBC about the allegations against her, saying that she had no need to release any personal data.

"I don't need to. I'm clean," she said in an interview on BBC Breakfast.

"I'm not being forced and almost abused into giving a knee-jerk reaction to something that goes against other people, who I trust."

She then explained that the sport's governing bodies have told athletes not to release data, and that by retaining her privacy she would "protect a lot of other innocent athletes".
