Paula Radcliffe has vowed to pressurise the World Anti-Doping Agency into applying tougher bans on drugs cheats.
The marathon world record holder has vowed to "make a stand" and has urged other athletes across the world to join her in pushing for a tougher line from WADA.
Radcliffe's comments come after the Court of Arbitration for Sport ruled that the British Olympic Association's lifetime ban for drugs cheats was unenforceable under WADA's anti-doping code.
That has paved the way for the likes of sprinter Dwain Chambers and cyclist David Millar to compete at this summer's Olympics in London.
Radcliffe said in the Daily Express: "This isn't about Dwain Chambers; it's a far wider issue. It's about a bigger deterrent being in place.
"If WADA is not listening to the world's athletes then we have to make them. Athletes have a voice. We can put pressure on WADA to make this tougher.
"I've always had a loud voice against the cheats and if we all do that we can make a difference. I will make a stand.
"I would like to think we could do it across the world. If all the athletes logged on to a campaign and signed their name to it, I'm sure we could do it."
