UK Sports wants Dwain Chambers to help them find drug cheats.

Every British athlete going to the Beijing Olympics will be drug tested at least once in the run-up to this summer's games.

UK Sport announced plans yesterday for the country's most comprehensive pre-Olympic testing programme, with more than 1,500 tests set to be administered on the athletes competing at the Olympic and Paralympic Games.

The programme started on January 1 and will last until the opening of the Olympic village in Beijing on July 27, 12 days before the opening ceremony.

From July 27, the World Anti-Doping Agency will supervise tests on all athletes in conjunction with the Chinese organising committee. About 4,500 doping tests will be carried out during the August 8-24 games, in line with the International Olympic Committee's zero- tolerance policy.

"Tests will be planned using our intelligence-based testing approach which focuses the allocation of tests around where they have a maximum impact in terms of detection and deterrence," said John Scott, director of drug-free sport for Britain's national anti-doping organisation.

"Obviously those in high-risk sports or disciplines can, and will, be tested more often. There is no limit to the number of times we might test an individual athlete."

Scott wants sprinter Dwain Chambers, who served a two-year ban for using the steroid THG, to help UK Sport co-ordinate and target its testing by giving full details of his former doping practices.

Chambers won a silver medal in the 60 meters at the recent World Indoor Championships in Valencia, Spain, but is ineligible for the Beijing Games because of Britain's lifetime Olympic ban on doping offenders.

"We certainly don't know who else was also in the know, whether there are people still in the system he worked with who have not been removed from that system," Scott said. "We don't know enough about the regime he pursued.

"We can offer Dwain a chance to help improve the system and stop people making the mistake he made, which, if he is truly contrite, is something he would want to do."
