Luan Gabriel was the youngest person to participate for Dominica at the London Games at age 16. She was making her first appearance in the quadrennial event. Gabriel qualified for the games via a wildcard because her fastest time between 1 May 2011 and 8 July 2012 of 24.09 seconds, set in Hamilton, Bermuda, was 0.79 seconds slower than the "B" qualifying standard for her event, the women's 200 metres. She took part in the contest's sixth heat on 6 August, finishing eighth (and last) of all runners, with a time of 24.12 seconds. Overall Gabriel ranked 47th out of 52 finishers, and did not progress to the semi-finals because she was 1.02 seconds slower than the slowest runner in her heat who made the later stages. After the games, Gabriel said she was concerned about her hamstring but felt "very proud" to be competing despite her preference of recording a faster time.
