Mayers received a two-year competitive ban from athletics after testing positive for excess testosterone in July 2005.

She was educated in the United States, attending Inglewood High School in California, before moving on to Los Angeles Southwest College.

[4] Mayers gained a place at University of Southern California and began competing for the USC Trojans women's track team.

She was cleared to race in May 2002 after initial eligibility issues and ran in the 100 m and 200 m at that year's NCAA Outdoor Women's Track and Field Championship.

She had a personal record run of 22.80 seconds in the 200 m qualifiers, the third fastest ever time for a USC athlete, and then went on to secure the 200 m NCAA title in the final.

[6] At the 2003 IAAF World Indoor Championships, she ran in the 60 metres and just missed out on a spot in the final, finishing third in her semi-final.

[8][9] She returned to St. Vincent in early 2005 and, while there, gave talks at local schools, promoting hard work and encouraging children to avoid the dangers of illegal drugs.

She reached the women's 100 m final and came away with the Commonwealth gold medal after a chaotic series of events: A dual false start by Laura Turner and Sally Pearson, saw just Turner eliminated and Mayers finished third for the bronze medal behind Pearson and Oludamola Osayomi.
