I seriously doubt that Armstrong would come out of retirement if there were even the remotest possibility of turning up a positive.
Besides, the new CERA test was known before Armstrong announced his plans.
Yeah…I'm not up to speed on CERA testing.
I'm pretty cynical when it cmoes to road racing and all top riders (past and prsent but especially Armstrong). I just can't believe one single athlete can dominate to the level he did (and may still do) when all his principal rivals (and many team-mates) tested positive. It sucks 'cause I got into the sport for it's beauty and pain (i.e. black and white pictures of Coppi going over some Italian mountain pass - later to find out that Coppi too was a doper!)but the doping controveries have sure affected my view of it.
