Can IOC win fight against drugs?

Olympic chief Jacques Rogge has asked "clean" athletes to blow the whistle on suspected drug-users in the sport.

But are athletics federations doing enough to rid the sport of the doping scourge?

In a BBC interview with British runner Paula Radcliffe, IOC president Rogge describes the need for co-operation to rid the sport of drugs.

Rogge says "There has to be an effort by the clean athletes to point their fingers at the ones who cheat and tell them: 'We don't want you in our midst.'"

Radcliffe is an outspoken campaigner against doping in the sport.

At the World Championships in August she famously held up a placard saying "EPO Cheats Out" as Russia's Olga Yegorova was allowed to compete even though she had failed a test for the performance-enhancing drug.

Is athletics doing enough to banish drug users from the sport? And is it practical to expect athletes to expose the cheats?

I think it is fantastic that Rogge has come out in support of brave athletes like Paula Radcliffe, who is not afraid to take a stand against drug cheats. However, it seems ironic that she was berated by officials at the World Championships for her placard protest, whereas now the IOC is encouraging athletes to speak out.

This idea will never work in reality. All that will happen is that athletes will cast aspersions on their main rivals to give themselves an advantage in the big races. This is asking for trouble.
