Like fellow Jamaican hurdler Delloreen Ennis-London she was not a successful hurdler until 2000, when she lowered her personal best by 65/100[clarification needed]. Having improved greatly, she finished eighth at the 2000 Olympics. At Athens 2004 she pulled out of the semi-finals.
At the 2008 Olympics in Beijing Foster-Hylton finished sixth in the final, but was only two-hundredths of a second behind the silver medallist.
Foster-Hylton's greatest achievement came in 2009 when she became World Champion at 100 metres hurdles at the World Championships in Berlin. She had previously won the 100 metres hurdles titles at both the Pan American Games (in 2003) and the Commonwealth Games (in 2006).
She has been married to Patrick Hylton, the group managing director of National Commercial Bank Jamaica, since 2005.[1][2][3]
