Reesha won a bronze medal in the 4 × 400 m relay at the 2007 South Asian U20 Athletics Championships.[3] At the 2007 1500 metres World Championships, Reesha finished 12th in her heat and did not advance.[4] In March of the following year at the South Asian Athletics Championships, Reesha set the Maldivian record in the 4 × 400 m, running 4:35.43 seconds to place 4th.[4]
Reesha was coached by Ahmed Faail, and had to train on a soft sand surface because she didn't have access to a synthetic running track. She said, "we can't compete with people from other worlds" and was hoping to run a personal best at the 2008 Olympics.[5] She did improve upon her best, running a time of 2:30.14 to finish 7th in her Olympic heat.[6] Reacting to her performance, she told reporters "I ran a personal best? Really? I am so happy". The Olympic running track was particularly hard on her feet because it differed from the sand she had trained on.[7]
At the 2009 World Championships in the 800 m, Reesha ran another personal best of 2:28.00 minutes to finish 7th in her heat. The time was also a Maldivian record.[4][8]
