Mexican hangs up her spikes
Former 400 metres world champion Ana Guevara has retired from athletics because of differences with the Mexican Federation.
After finishing fourth at last year's world championships, Guevara threatened to boycott the Beijing Olympics if changes were not made to the Mexican Athletics Federation board.
And the 30-year-old has now taken the decision to retire after being accused of 'bad mouthing' the board in an effort to cover up her flagging career.
"It was a personal decision after a lot of years of impunity," she said.
"My career has been always clean. In all these years I have forced myself to be at the top and I have worked very hard.
"I feel dismayed, offended; the little hunger for glory I had left disappeared after Osaka, when I had access to a lot of information about the board's performance.
"My retirement is definitive. I don't want to carry on. There is no chance of setting anything up because I lost my confidence in them."
Guevara's finest hour came with victory at the 2003 world championships in Paris, while she also won silver the following year at the Olympics in Athens.
