British javelin record holder Goldie Sayers says she has considered not competing at August’s Rio Olympics if Russia are allowed to take part.
Russia’s athletes are currently banned from international competition after allegations of state-organised doping.
Fourteen Russian athletes have since failed doping re-tests from Beijing 2008, but sports minister Vitaly Mutko says the ban should be lifted.
But Sayers, 33, said: “I think they should remain banned.”
She told BBC Sport: “I’d almost go as far as to say I wouldn’t want to compete in Rio if Russia were competing.
“But if they are reinstated and I didn’t compete I’d be cheating myself out of another opportunity at the Olympics.”
Sayers finished fourth in her event at Beijing 2008, but silver medallist Maria Abakumova has been named by a Russian television channel as one of the 14 athletes whose re-tests were positive.
High jump bronze medallist Anna Chicherova, 33, has vowed to clear her name after learning her sample failed.
The International Olympic Committee (IOC) said it would not be revealing the names of athletes who had returned positive results until B samples had been tested and individuals informed.
Sayers said she would be “happy” about being awarded a retrospective bronze medal, but also “immensely angry” at missing out on a place on the podium eight years ago.
“I think my career would have taken a totally different trajectory, no doubt,” she said.
“It’s not the same if you receive a medal through the post,” Sayers told BBC Radio 5 live.
Up to 31 athletes from six sports could be banned from competing at the Rio Games following the retesting of 454 selected doping samples from the Beijing Games.
