Jamila Lunkuse was the youngest person to represent Uganda at the London Games at the age of 15. Like Mugula she qualified for the Games via a FINA awarded her a universality place because her fastest time of 28.34 seconds was not within the "A" or "B" qualifying standard times for the women's 50 metre freestyle. Mugula stated that while the swimmer had talent, obtaining a medal would be "a tough call" because of her age and inexperience. Lunkuse took part in the event's fifth heat on 2 August, finishing eighth and last of all swimmers, with a time of 28.44 seconds. She finished 52nd out of 73 swimmers, and did not qualify for the semi-finals because her time was 3.16 seconds slower than the slowest competitor who progressed to the later stages.
