Paula Radcliffe, the world record-holder in the women’s marathon, is urging the makers of a documentary film about doping in athletics to reveal its list of suspicious blood samples to the International Association of Athletics Federations, according to an article in The Telegraph newspaper in the UK.

The German documentary titled “Top Secret: How Russia Makes Its Winners” shocked the running world in November with accusations that 99 percent of Russian athletes use banned substances as part of a state-sponsored doping regime.

Radcliffe, who will run in the London Marathon for the final time in April, is a seven-time world champion in track, cross country, the half marathon and marathon. She’s been a strong advocate of the anti-doping movement and has advocated a system where first-time offenders are banned for four years.

But doping suspicions have hovered over her since before she clocked a 2:17:18 and broke the women’s marathon world record by a minute and a half at the 2002 Chicago Marathon. She set the current world record of 2:15:25 at the 2003 London Marathon.

Radcliffe says the news about the documentary and the recent doping revelations about Rita Jeptoo and Liliya Shobukhova have only increased the chatter.

“It’s horrible. I get it all the time. People say, ‘she couldn’t have run 2:15 clean’” Radcliffe told The Telegraph. “I know I can be totally proud but it does make you angry and it does make you think we have to put a system in place that protects those athletes. On the one hand you think people can say what they want because you know inside, but it’s still not nice to have people saying that.”
