Has there been many or any Japanese marathoners that have been popped? If there haven't been any or many, then that's pretty remarkable, and admirable.
Most Japanese marathoners don't train at altitude, right? They just do heavy milage?
As to whether they're clean or not, I would like to believe they are, and do believe they are.
Also, as was said, if they are doping, you would think they would be beating the Africans. And winning Berlin and Boston every year, and New York.
Since they aren't doing that, I would assume they aren't doping. Or doping doesn't work. Or everyone is doping and the Africans are still beating everyone anyway.
One of those scenarios, pick one.
That's the only instance I could find.
