The delegation included two track and field athletes, Jidou El Moctar and Aicha Fall, who were selected to the team by wildcard places, as the nation had no athletes that met either the "A" or "B" qualifying standards. Moctar was selected as flag bearer for the opening ceremony while a LOCOG Games Maker carried it for the closing ceremony. Neither of the two athletes progressed beyond the heats.
