During the men's C4-5 road cycling event on 17 September 2016 at the 2016 Summer Paralympics, Golbarnezhad suffered a head injury during a collision with a rock on a mountainous stretch of the circuit in Pontal, a small peninsula and beach area in the Recreio dos Bandeirantes neighborhood of western Rio.[9][10][11] Golbarnezhad was treated on-site, and was in the process of being transported to the athletes' hospital when he died from a cardiac arrest. The Union Cycliste Internationale (UCI) announced that it would investigate the incident, and the I. R. Iran National Paralympic Committee requested a report on the incident from the IPC. Golbarnezhad's death marked the first time since the 1960 Summer Olympics that an Olympic or Paralympic athlete had died during competition.[12][13]
