C4 is designated for cyclists with lower limb impairments, such as cerebral palsy or amputations, while C5 is for those with less severe impairments.
In the para swimming S9 category, Ugo Didier of France emerged victorious in the 400m freestyle final, securing France's first gold medal of the Games.
