Benjamin Enzema was the only male athlete representing Equatorial Guinea at the London Olympics. He had not previously competed in any previous Olympic Games. Enzema qualified for the Games via a wildcard because his best time of 1 minute, 56.23 seconds, set at the 2012 African Championships in Athletics, was 9.93 seconds slower than the "B" standard entry time for the men's 800 metres. He was drawn in the event's seventh heat on 6 August, finishing seventh out of eight competitors, with a time of 1 minute, 57.47 seconds. Overall, Ezema finished 49th out of 52 athletes, and failed to qualify for the semi-finals since he was 11.05 seconds slower than the slowest athlete in his heat who advanced to the later stages.
