IAAF set to renew drug row

The World Championships could be overshadowed by more drugs controversy here later today as the IAAF prepare to release the details of tests for the performance enhancing drug EPO.

Seven distance runners, including Russian 3,000 metres indoor champion Olga Yegorova, are waiting to find out the results of samples given at the start of the championships.

They were part of a batch of 50 taken last week and although there is no suggestion that their initial blood samples have been returned as positive, back-up urine tests were deemed necessary.

Yegorova, who has caused a storm here after she was reinstated here having failed a test for EPO at a Golden League meeting in Paris last month, will be told whether she will be allowed to compete just hours before the opening heats of the 5000m.

If she runs, Britain's Paula Radcliffe has said it could spark protests from other runners.
