Paula Radcliffe believes that the 'tide is turning' in the battle against drug cheats, ahead of this summer's Olympics.
The marathon world-record holder has been outspoken of drug cheats in the past, and although she readily admits that there still is a problem, the 34-year-old believes that the authorities are starting to get the upper hand.
"There will be cheats, but the tide is turning," she told Sky News. "We need to concentrate on what we can do to improve the testing and on what we can do to improve the moral side of it as well.
"We need to teach athletes all across the world that to have pride in your performance, to be able to look back at the end of your career and to be proud of what you've done, you have to have done it cleanly and have to have done it fairly."
Radcliffe is also keen to make up for her disappointment in the Olympics, having failed to make the podium in three previous Games.
"I've still got unfinished business with the Olympics," she added.
"I haven't been a failure in all the Olympics I've been to, but I just don't think I've quite achieved what I'm capable of yet, and I just hope that I can achieve that this time."
