The distinction is more subtle than you suggest by alluding to historical problems caused by poorly designed drug regimes. If 'harm' were the only criterion which distinguished cheating from not cheating, training would be banned beyond a certain level. The stress caused by a heavy training block have short term and long term effects on some aspects of health which are of similar magnitude to the harms caused by some proscribed agents.
