Where did Alberto Contador have the test for the banned substance? [originaltext

Spain’s Alberto Contador, who won the Tour de France this year for a third time, has failed a test for a banned substance.The test was carried out on a rest day during the tour.Contador, a three-time Tour de France winner, tested positive for the banned substance Clenbuterol on the final rest day of this year’s race.Contador himself has made this positive result public, and he alleges that food contamination is the only possible explanation.The UCI, cycling’s world governing body, have said the B test confirms the first result, and they have suspended the cyclist while they carry out further scientific investigations.In a statement, they described the traces of Clenbuterol as being “a very small concentration”, 400 times less than the amount WADA -accredited labs must be able to detect, but they are still looking into what they describe as an “adverse analytical finding”.If the results are upheld, Contador could lose his Tour title and face a two-year ban from cycling.
