I don’t believe for a second, that Lemond was riding clean.
He may have thought he was riding clean, but think about it.
He was riding for a French team, with one of France’s biggest cycling stars, who was a proven doper, at the height of the doping era.
He did what the team directors told him to do, or he didn’t ride for the team.
I’m sure, there were very few questions asked at that stage of his career.
He probably always thought the reason he felt so good the next day, was because he was young and invincible.
