Depends if you believe that the majority are still doping, I don’t. If you look at the average speeds in road racing over the last 10 or so years they have dropped noticeably. Factor in the improvements in bike technology and it appears to me to say that doping is no longer as mainstream as it was.
Sure people still use PID’s but they are the minority. The real issue I believe is the lack of scrutiny in almost ever other sporting discipline. I know football is rife with doping, and tennis it is highly likely due to the vast number of competitions and the benefits in recovery that they can offer.
Greg Lemond has made some interesting observations about doping = boring racing but I’m not sure i agree…
