CASLAV, Czech Republic — In 1983, at age 32, when most track athletes are beyond their fastest times, Jarmila Kratochvilova ran 800 meters in 1 minute 53.28 seconds. The result was so blistering and unprecedented that it has become track and field’s longest-standing outdoor world record.

And perhaps its most suspect.

Kratochvilova (KRA-toke-vee-lova) is 66 now, a pensioner and a youth coach here in rural Bohemia, about 65 miles southeast of Prague. She has been retired from competition for three decades. But her career may soon be shaken retroactively as track and field officials attempt to restore credibility to a sport hit by repeated doping scandals.

European Athletics made a striking proposal in May to have the sport’s global governing body void all world records set before 2005. That year, storage of blood and urine samples began for more sophisticated drug screenings. Forty-five outdoor records are at stake, including Florence Griffith Joyner’s women’s records at 100 meters (10.49 seconds) and 200 meters (21.34) set in 1988.

In announcing the “radical” recommendation, Svein Arne Hansen of Norway, president of the European track association, said, “Performance records that show the limits of human capabilities are one of the great strengths of our sport, but they are meaningless if people don’t really believe them.”
