Athletics: Ohuruogu's appeal warning

Christine Ohuruogu will appeal against the one-year ban she has received for missing three drug tests and the Olympic ban that punishment has triggered under British Olympic Association by-laws. Should the 22-year-old Commonwealth 400 metres champion fail to persuade the BOA to rescind their ban, she says she will retire from the sport.

"The first point is to appeal against the Olympic ban because I think that is completely out of line," said Ohuruogu, who fell foul of regulations instituted in July last year requiring competitors to be available for random drug-testing during a specified hour on five days of each week.

"If what they're looking at is an Olympic ban, I don't see the point in me running again. That's what will destroy me the most. If that's the case, I probably will never run again."

But the UK Athletics president, Lynn Davies, says Ohuruogu will find it tough to overturn the ban. "There isn't a lot of room for manoeuvre," he said.
