Marion the mum back in quick time

Marion Jones will run her first competitive race less than two months after giving birth.

The Olympic 100 metres champion, who gave birth to her first son, Tim jnr, on 30 June, is planning to shock the athletics world by competing in the Brussels Grand Prix on Friday 5 September. The news was revealed by her partner, world 100m record holder Tim Montgomery.

"She really misses running," he said. "I love to see the thrill she gets from it. She wouldn't come back unless she was in the form to win races. But she's getting ready now, she's excited and she's happy. She means to be there." Montgomery was speaking ahead of tomorrow night's Norwich Union London Grand Prix at Crystal Palace, where he will be competing against Britain's Dwain Chambers and Mark Lewis-Francis.

Montgomery is in drastic need of a convincing performance before the world championships in Paris later this month.

On Tuesday night in Stockholm he flopped badly, finishing sixth in a time of 10.37sec - almost 0.6sec slower than the world record he set in September last year. He said: "I felt so calm and relaxed in Stockholm that my body just went to sleep."
