Simone Biles is the most decorated gymnast, male or female, in history. She won her first world championship all-around gold medal in 2013 and has not lost an all-around competition since.
She arrived in Paris with 37 medals from World Championships and Olympics, including 27 golds.
She has since added to this total, winning team gold – her eighth Olympic medal – and she looks set to increase her tally when she competes in the finals for all-around, beam, floor and vault.
