Road Cycling - what's with all the drug cheating ?

[P-Jay]

Just been reading about TDF winner Contador getting nabbed for it. Lance love-him-or-hate-him Armstrong being stringly linked with abuse and not a day goes by on Bikeradar without a headline about some other 'roadie' being caught out cheating and banned.

I have to admit I know nothing of road riding, I'm a off-roader through and through.

But what's up? I don't know of a sigle other sport with such outrageous levels of abuse.

Is it's the UCI zero tolerance approach or is it just as bad as it seems?

I'd love to know what the road riding fans think about it.
