Hamri was described as a childhood tomboy by her mother, and enjoyed playing football with the other children in her neighbourhood.[3] When the Tadjar family moved into their building, their daughter, who was an athletics coach, spotted in potential in Hamri.[4] After her first training session Hamri fell for the sport, and spent the next few years moving through different clubs, but it was later noticed that her vision began to deteriorate and her illness was confirmed by a doctor.[4]
Due to her failing eyesight, Hamri was classified as a T13 athlete and in 2007 she represented Algeria at her first major international competition, the 2007 All-Africa Games, where she won a bronze medal in the long jump.[3] The high-point of her career came at the 2012 Summer Paralympics in London, where she qualified for both the 100 metre sprint (T13) and the long jump (F13). Despite posting a season's best in the sprint, Hamri was unable to progress through to the finals. Her efforts in the long jump paid greater dividends with a distance of 5.31m winning her the silver medal.[2]
Further success followed over two successive IPC Athletics World Championships, 2013 in Lyon and 2015 in Doha where, now classified as a T12 athlete due to her condition worsening, she won two silver medals in the long jump event.[2] At the 2016 Summer Paralympics in Rio de Janeiro, Hamri again entered the 100 metre sprint and the long jump. In the 100 metre heats, she qualified as a fastest losing athlete, but then failed to qualify through the semi-finals. Her success, as in London, came through the long jump, where she finished in bronze medal position, with a jump of 5.53 metres.[2]
