The delegation consisted of eleven track and field athletes that included Moses Ndiema Kipsiro, Benjamin Kiplagat, and Stephen Kiprotich, one each in badminton and weightlifting (Edwin Ekiring and Charles Ssekyaaya), and two swimmers (Ganzi Mugula and Jamila Lunkuse).

Ekiring, Ssekyaaya, Mugula, and Lunkuse had qualified through wildcard places, while the rest of the delegation satisfied the Games' qualification standards for their respective events.

[3] The delegation consisted of athletics competitors Jacob Araptany, Benjamin Kiplagat, Thomas Ayeko, Abraham Kiplimo, Geofrey Kusuro, Julius Mutekanga, Stephen Kiprotich, Moses Kipsiro, Janet Achola, Dorcus Inzikuru and Jane Suuto, badminton player Edwin Ekiring, swimmers Ganzi Mugula and Jamila Lunkuse and weightlifter Charles Ssekyaaya.

[10][11] In an interview with New York Press before the Games he said he promised to ensure that he would make the best of his participation: "When you’re running, you’re looking at improving your personal best time, so it doesn’t matter whether you win or not.

[13] Jacob Araptany was the youngest competitor to represent Uganda in the athletics discipline at the London Olympics, aged 18.

[16] Araptany finished 25th out of 37 competitors overall,[n 2] and failed to go through to the final because his time was 6.73 slower than the slowest runner in his heat who made the later stages.

[10][17] Kiplagat said that he wanted to finish in a podium position in the event and revealed that he was not worried about wet-weather conditions affecting his performance.

[16] Kiglagat led early on although he stumbled over the steeple in the penultimate lap but was able to regain his balance and finished at a slower pace.

[20] In the final, held two days later, Kiplagat fell and injured his knee after he was reportedly pushed by another athlete, and moved to the inside line while changing his tactics to stay away from the lead pack.

[21] Geoffrey Kusuro's participation in the London Olympic Games marked his début in the quadrennial event at the age of 23.

[3] He attained qualification to the Games because his fastest time of 13 minutes, 12.32 seconds, set at the 2011 Míting Internacional d´Atletisme Ciutat de Barcelona, exceeded the "A" qualifying standard for the men's 5000 metres.

[23] At the time of the 2012 London Summer Games Abraham Kiplimo was 23 years old and was making his first appearance in the quadrennial event.

[3] He obtained qualification to the Games because his fastest time, set at the 2011 Míting Internacional d´Atletisme Ciutat de Barcelona, of 13 minutes, 10.40 seconds was within the "A" qualifying standard.

[10][25] Three months before the Games started Kipsiro stated that he took the year the Olympics were held as "special" and was motivated for the event.

His foot was stepped on by another competitor while running in the middle of the pack with Kipsiro sustaining a bruised right hand, and felt pain in his shoulders.

[10][31] In preparation for the marathon Kiprotich spent time training in Kenya's Rift Valley Province alongside long-distance runner Eliud Kipchoge.

[33] Kiprotich gained on Kipsang and also joined Abel Kirui in a group of three runners until his Kenyan rivals established a small gap.

[10][36] She said the training that she received from coach allowed her to achieve success and set herself the objective of securing her first medal at an international event.

[3] 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,[10][39] and was the last Ugandan athlete to obtain qualification.

[40] 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.

[3] Ekiring qualified for the Games because he was granted the automatic qualification slot for one player in the African continent partly due to him being placed 98 in the BWF World Ranking in May 2012.

[46] Ganzi Mugula, who at the age of 33 was participating in his first Olympic Games,[3] was notable for carrying the flag of Uganda in the opening and closing ceremonies.

[50] Overall he finished 53rd out of 58 swimmers, and was unable to advance to the semi-finals after being 5.11 seconds slower than the slowest competitor who progressed to the later stages.
