The women’s 4x100m record set at London 2012 by Team USA runners Tianna Madison, Allyson Felix, Bianca Knight, and Carmelita Jeter had a big impact on the history of the women’s 4x100m relay as it erased a world record that dated back to October 6, 1985.
The quartet took more than half a second off the mark set by an East German foursome at a meet in Canberra, Australia that had been one of the longest-standing running records on the track.
It had also been a record looked at with much suspicion since the athletics world became aware of systematic state-sponsored doping by East Germany in the 1980s.
