Anti-doping chief admits the war on doping will never be won

DRUGS IN SPORT: World Anti-Doping Agency president John Fahey says the fight against doping will never be won but also says: "we must continue the fight".

The Australian ends his reign at the end of the year after taking up the role in 2007.

Athletics is currently central to that tussle having made headlines in recent weeks with the five positive tests at the Jamaican National Championships in June - which included former Olympic gold medallists Asafa Powell and Sherone Simpson - plus Tyson Gay's recently revealed positive sample from a test back in May.

Fahey says he will not discuss individual cases while ongoing but says: "What's occurred in that sport tells us that we haven't solved this problem. It's still alive and well."

Gay, Powell and Simpson had all argued they had unknowingly taken banned substances.

But Fahey hit back, saying: "Every athlete in the world is responsible for what goes in his or her system - that's the start and finish. Every athlete has to make sure they know what they're doing.

"My take is that no matter how big or great you are as a star and whatever your sport you're not beyond the capacity to be found as a cheat through the methodology adopted.

"Every time that we catch someone, as much as it's disappointing, it says to the cheats: 'You can't get away it, the odds are we will catch you.'"

The Gay and Powell news has followed widescale failed tests in Turkey and Russia, where this year's World Championships will be held, many of which were the result of retrospective testing.

This, in Fahey's eyes, is particularly key as it sends a message "to those that think you've got away with it, we will catch you".
