Angry Jones claims she is not spent force

MARION JONES has outlined her determination to prove wrong the critics who think she is a spent force in athletics.

The American track and field star had a torrid time over the last nine days at the US Olympic trials in Sacramento which ended last night, failing to qualify for the 100 metres and withdrawing from the 200m citing fatigue.

"I was extremely disappointed by the way I ran," Jones said of her 100m performance, when she finished fifth in the final on the first Saturday of the trials. "You want to run your best when you are supposed to. This is the most difficult Olympic trials in the world and you have to place in the top three or you won't go. It just didn't happen on the day for me."
