I've been a fulltime triathlete the last two years and haven't taken any PED's. I'm not racing elite, but not far off. My training buddies (of which two are elite) are clean to the best of my knowledge (lived with one so I think I would have found something dodgy). There are people competing clean, but its definitely a problem in top level sport. Nobody has been busted at this year's tour, but we're not out of the woods on that one yet. Reckon a few names will come up in the next few months, but hopefully none of the big guns like contador, armstrong, wiggins or cav.
I think there will be a lot that goes under the radar, but do not imagine athletes such as Bolt, Hoy, Phelps or Idowu take any. Saying that here have been a few suprises over the last 7-8 whereby athletes I thought did not take them have, but innocent until proven guilty and I would like to think that my fave sports stars achieve what they do through talent, rather than avec the aid of drugs. So I will keep on having that possible disillusion!
Alot are, there was a guy on other forums full of serious roiders who advised athletes in Olympics posting about all the different shite they take for different aspects of performance.
Even in events like shooting at Olympics they take downers to stop the shakes.
Yes it never ceases to amaze me the naivety of some people.
