Need to clarify a few things here.
Pedro Delgado in the ITT in 1988. It was too good to be truth.
Though probably took steroids earlier in the season for training, Delgado was a fine rider his entire career, and a former Vuelta winner. There was arguably weak competition in 1988 when he won the Tour. Roche wasn't there, LeMond wasn't there, Fignon abandoned. Hinault was retired. It was good, but not too good to be true.
Laurent Brochard winning Worlds...that mullett had to be on some kind of stuff. I've never seen hair that agro!
According to Willy Voet, Brouchard was actually positive for Lidocain after the race, and the doctors prepared a written document, but the issue was delayed at Hein Verbruggen's order until outside the time limit, and it never came to light.
Not a famous ride but Alexi Greywall admitted blood doping in his 1984 gold medal. Crazy, I remember watching that race.
Amazing that we get to 2 pages before anyone mentioned the 1984 American Olympic cycling team. Doped to the gills with blood transfusions, wasn't illegal in sporting terms at the time afaik but unethical for sure.
They weren't doped to the gills with transfusions, and no one on the road team used blood doping. Here's the article again detailing what happened
. Keep in mind the best four racers going into the race were arguably Davis Phinney, Steve Bauer, Dag Otto Lauritzen, and Alexi Grewal. They finished all in the top 6, beating riders like Bojan Ropret, Nester Mora, Paul Kimmage, Louis Garneau, etc. Raul Alcala was there and finished 11th. Jean-Paul Van Poppel was there, be had a mechanical and lost big time. Fabio Parra as well, but the course didn't suit him. The only other big name that performed poorly was Miguel Indurain, who was barely 20 years old and dropped. Because of the boycott, NO Eastern block racers of quality were there. Thus there was no great shock of the US riders performing so well at the time on their home turf. They all went on to have strong pro careers.
