So competition is no longer who is naturally best, but who has done the best job of artificially boosting their fitness, within the “regulation permitted limits”.
I wonder what some of the top scoring Olympic atheletes of the past 20,30 years would have scored, if the same individuals were competing “raw” as Olympic athelete (besides the Soviets, East Germans and Chinese) did long ago, like the 1930s maybe. Would they have been as “good” then as they were recorded as now?
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.
