But athletes will take EPO in Sydney because they can, and some of them will take too much of it. In 1995 Olympic—caliber U.S. athletes were asked in a poll, "Would you take a drug that made you a champion, knowing that it would kill you in five years？" more than half said yes. So even if we forget about fair play and credibility and Olympic ideals, we are left with this: the athletes must be protected from themselves arm the pressure to win. How？
The I.O.C. needs to do two things immediately: develop a spine, and federalize. The only way to catch a cheat is with unannounced, out-of-competition testing. Historically the I.O.C. has delegated decision making to individual sports federations, but that policy is not working when it comes to drags. A third of the 28 federations have yet to agree to out-of-competition tests in advance of the Sydney Games. The I.O.C. should call an emergency session and make a new rule applying to all sports, then send out its newly empowered testers.
As for that imperfect test for EPO-use it anyway. As gold medal marathoner Frank Shorter, now chairman of the U.S. Anti-Doping Agency, says, knowing a test is looming that will knock cheaters off stride. Shorter says that if there is no EPO test at Sydney, then every endurance or strength performance is suspect. He's right. And when sport becomes suspect—when no one believes in it—it's no longer worth watching.
