Walsh critical of biological passport

David Walsh, a leading investigagtor into the world of organised doping in porfessional cycling, belives that the biological passport system set up by the UCI, cycling's international governing body, fails to catch the cheats.

Walsh, who spoke at Play the Game 2007 in reykjavik, was initially positive about the passport scheme, though now has his reservations according to an interview with cyclingnews.com.

"The passport seemed like a good idea but I don't believe that the system can catch the sophisticated cheater. The evidence we have so far is that the guys towards the winning end of the classification in big races are still significantly ahead of the UCI's checks."

The biological passport records an individual cyclist's blood profile, allowing long-term profiles of riders to be built up and analysed for anti-doping controls.
