Dominica at the 2012 Summer Olympics

At the age of 27, Erison Hurtault was the sole male athlete representing Dominica at the Olympics.^[2] He previously participated in the 2008 Summer Olympics in Beijing.^[7] Hurtault qualified for the games because his fastest time of 45.59 seconds between 1 May 2011 and 8 July 2012, set at the 2011 Ninove Memorial Geert Rasschaert, was the exact "B" qualifying time standard required for his event, the men's 400 metres.^[8][9] Before the Olympics, Joel Hamilton felt the runner would progress beyond the first round and Hurtault's personal trainer was confident he was in good fitness.^[7] He was drawn in the seventh heat on 4 August, finishing fifth out of seven athletes, with a time of 46.05 seconds. Hurtault placed 31st overall out of 47 runners,^[a] and did not advance to the semi-finals after finishing 0.59 seconds slower than the slowest athlete in his heat who made the later stages.^[10] Afterwards Hurtault felt he could have finished higher but thanked the Dominican people for supporting him.^[11]

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.^[2] 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.^[8][12] 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,^[b] 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.^[13] 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.^[14]
