He was banned from the sport for two years after testing positive for performance-enhancing drugs in October 2008. On 25 May 2009, he announced his retirement from the sport, claiming that it is "impossible to win without doping" in international cycling.[2]
Doping
On 13 October 2008, L'Équipe announced that Kohl had tested positive for CERA (continuous erythropoitin receptor activator, a third-generation variant of erythropoietin, aka EPO) used during the Tour de France.[3] On the 15th he admitted his drug use.[4] His results were removed, but his third-place finish in the 2008 Tour and his first place in the mountains classification have not been remade. If they ever are Denis Menchov of Rabobank would become the third-place finisher, while Carlos Sastre of CSC–Saxo Bank, overall winner of the Tour, would become winner of the mountains classification. The next day, Silence–Lotto terminated Kohl's contract with the team.[5] Several journalists had also nominated Kohl to receive the Austrian Sportspersonality of the year award, but he was removed from the contenders list.[6] On 24 November 2008, Kohl was banned for two years by the Austrian anti-doping agency (NADA).[7]
His ex-manager, Stefan Matschiner, was arrested on 31 March 2009 in Austria and charged with selling doping substances. Kohl stated that he was "not surprised" by the arrest.[8]
In an exclusive interview with L'Équipe, the Austrian detailed how he "prepared" himself for the 2008 Tour and received blood transfusions from his manager during the event. The International Cycling Union 's (UCI) biological passport failed to prevent Kohl from practicing blood doping on a regular basis during his career, he said. "The top riders are so professional in their doping that they know very well they have to keep their blood values stable not to be detected".[9]
Kohl's results for the 2008 Tour de France have been removed in the official Tour de France results, but the definitive classification has not been published yet.[10]
