The "Good Luck Beijing" 2007 UCI BMX Supercross World Cup opend today at the Laoshan Bicycle Moto Cross (BMX) Venue, with Anne-Caroline Chausson of France coming out on top on both runs of the women's time trials qualification with a time of 37.446secs, and three US riders making a clean sweep of the top three places in the men's.

In the women's event, Caroline led the first run with 37.513secs, which was difficult for other riders to surpass. In the second run, she bettered her time with 37.446sec. After two runs the result table shows that even Caroline's time from the first run topped those of all her opponents, which shows her technical superiority in the women's group. The competition for the second and third places was fierce, with Sarah Walker of New Zealand finishing second in a time 0.004sec ahead of Shanze Reade of Great Britain, the third place finisher. Their contention in tomorrow's semifinals is expected to be another even more inten. Following them are riders from United States, Argentina and Czech Republic, who all showed their prowess today.

In the men's group, as many riders tried to get used to the track on their first run, the results turned out to be quite different. In the second run, however, all of them demonstrated their real strength, especially Mike Day, Kyle Bennett and Steven Cisar, who swept the top three places after two runs, their best results differing from one another by merely 0.1sec or so.

In tomorrow's semifinals it is very likely that one of them will emerged the winner. Following them today were two French riders, who are expected to join the contention for the top three spots.
