this record when Dutchman Jelle Nijdam averaged 52.375 km/h (32.544 mi/h) in the historical 24.5 km (15.22 mi) individual time trial from Versailles to Paris at the 1989 Tour de France. Doping Kelly failed drug tests twice during his career. After the 1984 edition of Paris–Brussels, in which he had finished third, cycling authorities stated that a urine sample supplied by Kelly had tested positive for pemoline (Stimul), a result which was repeated with the testing of a B sample. The Royal Belgian Cycling League sentenced Kelly to a three-month suspended ban and a fine. Kelly denied taking any banned substances: in an interview at the time with David Walsh, he claimed that there were "irregularities at the testing centre that day ... the medical control at Paris-Brussels was very badly organised and lots of people were in the room who had no right to be there ... in all this confusion something must have gone wrong". In his autobiography Hunger, Kelly stated that Irish Cycling Federation official Karl McCarthy, who acted as a witness on Kelly's behalf at the second test as he was unable to attend due to racing commitments, told him that the B sample was "tiny" and below the amount required for the test. In his book Massacre à la chaîne: Révélations sur 30 ans de tricheries (Chain massacre: Revelations on 30 years of cheating), Kelly's former soigneur Willy Voet claimed that Kelly had been ill with bronchitis in the week before the race and had taken ephedrine to treat it: to avoid a positive test, Voet wrote that Kelly had carried a container in his shorts filled with urine supplied by one of the team's mechanics to doping control, and that the Stimul detected in the sample had been taken by the mechanic to help him stay awake while driving the team's truck. Kelly's second positive test occurred at the 1988 Tour of the Basque Country, where he tested positive for codeine. Having finished fourth in the overall classification, he received a ten-minute penalty that dropped him down the order. Kelly explained this as being the result of a worsening cough he had developed during the race: he said that between the end of the final stage and attending doping control he took a swig from a bottle of cough medicine, to which he attributed the presence of codeine in his urine sample.
