100m world record

Gerald Phiri, a former 100m Olympian, has been caught at the centre of a doping scandal involving three high-school athletes

The world record holder thinks he could have lowered his time of 9.58 in the 100m final at the 2011 World Championships in South Korea—however, he was disqualified for a false start

The world 100m champion appeared on The Tonight Show with Jimmy Fallon and said he wants to become the first male sprinter to win four Olympic gold medals
