Flo Jo was the most obvious. Absolutely destroys the 100m world record in the QF's of the American trials (which hasn't looked like being broken since), then wins the Olympics at a canter before retiring. I'm pretty certain it wasn't just co-incidence that testing was coming in immediately after the 1988 games :hey
It was only the sight of Tommy Simpson laid across the tarmac on Ventoux that made cycling authorities look at what they were doing. The hydration policy, limiting the number of bottles of water a rider could have, was ****ing insane.
Thats basically what happened to Simpson. The rule was that you could only carry 4 half litre bottles of water with you, in summer, and when tour stages were 2 or 3 times longer than they are now. Simpson had been seen at the bottom of the mountain in a Tabac drinking brandy to calm his stomach...this when mixed with the obvious dehydration and amphetamine was a recipe for disaster. They found an empty tube of amphetamine in his jersey along with two full ones.
And yet he couldn't give up. His last words: "Put me on my bike'' :-( His body was completely spent. And think of the bikes they were riding back then :-( Terrible.
