HAVING just smashed her own 3,000 metre world record by 6.1 seconds, Wang Junxia would have been forgiven for collapsing exhausted on the track at Beijing's Workers Stadium.
But the 20-year-old ''supergirl'' from northeast China looked no more out of breath than if she had just jogged around the corner to pick up the morning newspaper.
Surrounded by press photographers and cheering fans, Wang's face betrayed no emotion, not even a slight smile, as she slowly made her way back to the changing rooms. It seemed that for her it was just another day.
But everybody watching Monday's race, broadcast live on national television, knew they had just witnessed something quite extraordinary.
The feat was all the more remarkable because Wang had only the day before knocked 10.4 seconds off the existing world record, set by the Soviet runner Tatiana Kazankina nine years ago.
THAT remarkable feat had followed a 10,000 metre race a few days earlier in which she took a staggering 41.91 seconds off the existing world record.
