Barber represented Trinidad and Tobago at the 2008 Summer Olympics in Beijing, where she competed in the women's 100 m hurdles. She ran in the fifth and final heat against seven other athletes, including Jamaica's Brigitte Foster-Hylton, and United States' Dawn Harper, who later dominated this event by winning an Olympic gold medal. She finished the race in fourth place by two hundredths of a second (0.02) behind Kazakhstan's Anastassiya Pilipenko, with a national record-breaking time of 13.01 seconds. Barber, however, failed to advance into the semi-finals, as she placed eighteenth overall, and was ranked below two mandatory slots for the next round.[4]
