What do you mean by 'chemically'? I just finished Christophe Bassons' book, so I suspect doping.
I agree that they are amazing athletes, dope or no dope. I'd prefer no dope, and I wish I could be sure that the cyclists are clean, but ... I suspect dope.
My time for my 7/13/86 ride was the same as LeMond's, as reported by the Chicago
Tribune. Coincidentally, my distance was exactly half of LeMond's (also per the
Trib). I'm pretty proud of that ride.
