Sebastian Coe wants the current generation of athletes to finally take down world records from the 1980s which he concedes “may not be the safest on the book”. The issue has become a major talking point in Eugene after Shericka Jackson ran a stunning 21.45sec to win world 200m gold, a time that put her second on the all-time list behind Florence Griffith Joyner. The controversial American, who also broke the 100m record in an era when drugs testing was sporadic, died in 1998.
