Oman at the 2016 Summer Olympics

Al-Harthi qualified for the Olympics with a time of 10.16 seconds at the 2015 Military World Games.^[6] In 2016, his Olympic qualifying time of 10.05 seconds was 0.11 seconds faster than the required time to enter the men's 100 metres.^[17][18] On 13 August, Al-Harthi did not appear in the preliminary round and competed in the sixth race of the heats.^[19] Al-Harthi finished in third in his heat with a time of 10.22 seconds.^[20] His placing meant Al-Harthi did not qualify as one of the first two runners in his individual heat. As he also did not have one of the eight fastest times from the remaining runners, Al-Harthi did not progress to the semi-finals.^[21] Out of 84 competitors, Al-Harthi finished in a tie for 26th place overall.^[22]

Mazoon Al-Alawi entered the 2016 Olympics as a wild card.^[23] Her entry time of 12.04 seconds was 0.72 seconds slower than the Olympic qualifying time for the women's 100 metres.^[18][24] On 12 August, Al-Alawi finished third in the second heat of the preliminary round with a time of 12.30 seconds, which qualified her as one of the two fastest remaining runners following the top two finishers of all of the heats.^[25] In the subsequent round (held the same day) Al-Alawi came in eighth in the seventh heat.^[26] She did not automatically advance to the next round as she did not finish in the top two of her heat and, with a time of 12.43 seconds, she was slower than the next eight qualifiers and so she did not progress past the heats.^[27] Al-Alawi finished 62nd overall out of 80 runners.^[28]

Before the Olympics, each shooter required a Quota Place and Minimum Qualification Score.^[29] With invitations from the Tripartite Commission, Quota Places were given to Hamed Said Al-Khatri and Wadha Al-Balushi.^[30][31] To qualify for the men's 50 metre rifle three positions event, shooters needed at least 1135 points.^[32] Al-Khatri reached his requirement by scoring 1149 points at the 2014 ISSF World Shooting Championships in this division.^[33][34] For the women's 10 metre air pistol Olympic event, qualifiers needed 365 points or more.^[32] During the 2015 ISSF World Cup, Al-Balushi accumulated 381 points and reached her score requirement.^[35][36]

At his qualification round on 14 August, Al-Khatri scored 1138 points during the 50 m rifle three positions event.^[37] While achieving 397 points in the prone position round for his highest score, Al-Khatri scored 40 ten-pointers during the three rounds, but his score was too low to make him one of the eight qualifiers for the final.^[38] Out of 44 competitors, Al-Khatri finished overall in 43rd.^[39]

On 7 August, Al-Balushi scored 379 points during qualification at the 10 m air pistol Olympic competition.^[40] While scoring five ten-pointers throughout the four rounds, Al-Balushi's highest score was 96 points in the third round. As she did not have one of the eight highest overall scores, Al-Balushi did not qualify for the final.^[41] Overall, Al-Balushi finished 26th out of 44 competitors.^[42]
