At the 2016 Summer Olympics, Azemia competed in the 400 metres hurdles. Azemia, who was the youngest Seychellois athlete at the Games, was drawn in heat three, a heat containing the London 2012 bronze medalist Javier Culson. In the race on 15 August 2016, Azemia ran a time of 50.74 seconds. Azemia's time was a personal best (beating his previous best of 51.09), and a new Seychellois national record. It was also a new Seychellois national junior record. After the race, Azemia told the Seychelles News Agency that "he knew going into the race that it would be difficult to qualify for the next round, but he was nevertheless happy with his performance". Seychelles Athletics Federation secretary Wilfred Adrienne said that, "It [the race] was great, an impressive performance for someone his age at such a high-level competition and we [the Seychelles Athletics Federation] are proud of him". Azemia's time was the 43rd-quickest out of 47 athletes. Azemia's time was 0.97 seconds slower than the slowest athlete to progress to the next round and, therefore, he was eliminated.
