Maoulida Darouèche was the only male athlete representing Comoros at the London Olympics. He had not previously competed in any Olympic Games, but was notable for being his country's flag bearer at the opening ceremony. He qualified for the Olympics via a wildcard as his best time, 51.93 seconds, set at the 2011 Chambéry Meeting National, was 3.13 seconds slower than the "B" qualifying standard for his event, the men's 400 metres hurdles. Darouéche competed in the men's 400 metres hurdles on 3 August in the fourth heat of the first round, finishing ninth (and last) out of all competitors with a time of 53.49 seconds in a heat led by Javier Culson of Puerto Rico (48.33 seconds). Overall he finished 46th (and last) out of all entered athletes, and was 4.31 seconds slower than the slowest competitor that progressed to the semi-final stage and, therefore, that was the end of his competition.
