100m dirty+ possibly wind aided (Flo-Jo)
200m dirty (Flo-Jo)
400m filthy (Marita Koch, 9 out of the top 10 fastest times ever were set between 82-86 by eastern block countries known to systematically dope)
800m dirty (Jarmila Kratochvílová, same story. hopefully Jemilo is legit)
1500m dirty (top 4 times EVER from 2 small meets in China, hmmm)
3000m filthy (one small meet in China, 2 unknown chinese break the wr in a heat, 3 more in another heat and then 5 in the final, the winner going 15 seconds under the old WR, all in the same day)
5000m clean! (Meseret Defar and Dibaba are probably clean)
10000m dirty+possible lap miscount (2 chinese go under the world record, one of them by 40+ seconds, plus of course the meet was in Beijing just 4 days before the 3000m wr. There is no video footage of the race, no first hand race reports, I believe there were no iaaf officials, just Chinese ones and many people speculate that they did not run 25 laps or that it was a short track.)
1/2 and full marathon=clean
SO there you have it, most of the womens records are filthy dirty because they were ran either by eastern block athletes systematical doping, Chinese who ran behind closed doors and sipped turtle soup, or an American who turned into a beast in one year and dropped 1/2 a second off of her Pr and probably had doubtful timing to boot.
Good job Iaaf, you rock.
