There are medals for Jason Queally and Chris Hoy in the kilometre at the World Track Champs in Los APIC BY TDWSPORT.COM Theo Bos of the Netherlands frustrated the best-laid plans of Chris Hoy and Jason Queally, both of Team GB, to round off a spectacular evening for Dutch track cycling with victory in the kilometre time trial at the world championships in Los Angeles. While Bos's burst took gold, his compatriots Teun Mulder and Levi Heimans, scored further success, with a first gold in the men's keirin and a bronze in the individual pursuit, respectively. Bos shunted Queally out of gold medal position and left an out-of-sorts Hoy, the last man off, with a lot to do to retain the world title that he won in Melbourne last year. On that occasion Bos was third, and in Athens at the last Olympic Games, the Dutch prodigy could only manage fifth place as Hoy stormed to a thrilling gold medal. But this time things were different. In the Carson velodrome, it was the blond-haired Bos who was the man to beat, with a time of 1:01.165. Hoy, last off could not match the Dutchman's time and was even eclipsed by that of Sydney Olympic champion Queally, who notched a 1:01.230. While Bos celebrated, a visibly disappointed Hoy, who clocked 1:02.260 for the bronze medal, was left to count the cost of a winter spent fulfilling the obligations of an Olympic champion. "Obviously," said Hoy, "I never like to lose a race, especially a world championships. But that's life. I've had to juggle a few other things this year in addition to my cycling. I thought I might be able to pull if off but unfortunately not." "I'll make sure I come back next year with a renewed focus," said Hoy. "I've always felt that I've learned more from my defeats than my victories. I'll have a serious look at what went wrong - the Commonwealth Games next year is a big event for me so I want to be at my best for that." The young Dutch squad enjoyed a breakthrough night. In the men's individual pursuit, Heimans's bronze was his nation's first in the discipline at this level. Mulder's success in the Keirin was also a first and came against a quality field, that included the outgoing world champion Jamie Staff (GB), who finished fourth behind Mulder, Barbados' Barry Forde and Australia's Shane Kelly. In other events, Vera Carrara of Italy won the women's points race from Olga Slyusareva of Russia and Kathy Bates of Australia. But even allowing for the successes of others there was no doubt that it was a great night for the Dutch, who currently lead the medal table, five medals to three, from Great Britain.
