I tend to side with BigBoat here. I wouldn't be too surprised if Lemond took corticoides while riding for Guimard, or under that, as "medicine" for injuries. Maybe he didn't. Maybe he were told they were vitamin B, who knows. But he wasn't on EPO, blood doping, amphetamines or steroids.
By all accounts, from many riders, teammates, DS's, etc. Lemond was if not entirely clean, very close to it. He's never been seriously accused or involved in any doping situation of any sort. LaVie Clare DS Paul Kochli was anti-doping, and didn't want corticoids or doping products of any sort even around his team. This has been verified by many. The team was sponsored by a health food chain, and wanted no problems, and Kochli agreed.
Next, despite what people wonder, from about 1975-1990 things were relatively clean in the peloton. Relatively. You did have riders on amphetamines and corticoids, and eventually steroids. But those simply don't give you the gains that O2 boosters do. More like 2-3%, and yes, Lemond was that much more talented. So was Hinault. When Delgado tested positive for probenicid in that strange set of circumstances in 1988, it was widely assumed not that he was on steroids or testosterone like Floyd was microdosing, but that Delgado had taken something in the early season to keep his strength up, and they gave him the probenicid "just in case" because it wasn't on the list yet. Steroids were thought back then to build too much muscle too easily. It really wasn't until a decade later that they were commonly accepted as really helping endurance athletes on a frequent basis. People talk about the 1984 Olympic team blood doping, or Lasse Viren, Waldemir Cirpinski or the DDR using blood packing. This was definitely true, but no where near as sophisticated as it has been in cycling in recent years. Not even close. What cyclists blood doping there were back then, were very isolated, and likely minimal.
Armstrong fans dismiss this, but to me there is a certain ring of truth in listening to Lemond talk now that appears genuine and can't be faked. Again, not saying he was whistle clean, maybe he was, but he knew what was going on, still has some connections, and is a very good student of the sport. I think the vast majority of what he says is accurate.
Good philosophical post Blackcat. Aristotle would call that the
false syllogism.
