Thus you speak of the 'problem' with Professional Cycling in the past and still apparently present in the present (word play)! Seven time Tour de France victor Lance Armstrong was stripped of those 7 victories BUT they were not awarded to anyone else who competed. The reason is/was that every one of his close competitors had also been found, at one time or another, to have been doping. His team just was better at timing and hiding the doping.
This year, the Tour's 4-time victor, Chris Froome, was within a week of being banned for testing too high for a legal asthma drug in a 2017 drug check. However, at the last minute, the UCI (International Cycling Federation) and the drug testing agency gave him a pass for participating in this year's race. Froome's team, SKY, is the best funded and strongest at the race and he is currently 2nd behind his own teammate, Geraint Thomas, with a week left in the 3 week race.
I guess my argument can be an excess, as you look at the advancement in equipment allowed to be used today, particularly in winter sports and even professional golf.
With the kind of many different super-engineered/designed golf glubs today, it is no wonder more amateurs even are playing better golf than they did just 20 years ago. You can pay hundreds, or even over $1,000 for a single techniloggically specially engineered golf club today, not a set, just one club. And, as a spectator I love golf. So I guess I should just stop complaining about “cheating” in sports.
Then again, when we talk about equipment, as all participants can get it, we are not talking about drugs made to improve the physical performance of the human body.
So maybe my complaint is ok after all.
