Dorcus Inzikuru was one of the oldest athletes to compete for Uganda at the London Olympic Games at the age of 30. She was the only one of the team's athletes to have taken part in the 2004 Summer Olympics in Athens. Inzikuru gained qualification into the London Games by winning the 3,000 metres steeplechase race at the 2012 International Athletics Bottrop Gala, with a time of 9 minutes, 30.95 seconds, which was 12.05 seconds faster than the "A" qualifying standard for the women's 3000 metres steeplechase, and was the last Ugandan athlete to obtain qualification. To prepare herself for the Games she trained in Iten, Kenya. Inzikuru said that if she performed well at the Games it would allowed her to participate in European events after finding it difficult to obtain visa to travel to the continent but did not promise any medals. She was placed in the third heat on 4 August, finishing seventh out of 14 runners, with a time of 9 minutes, 35.29 seconds. She finished 20th out of 44 runners overall, and did not qualify for the semi-finals because her time was 5.43 seconds slower than the slowest qualifier in her heat.
