The 27-year-old is one of the most recognisable stars on the planet and her return to the Games was hugely anticipated.
She was forced to withdraw from a number of events in Tokyo three years ago after developing ‘the twisties’. Something likened to the yips in golf or baseball.
Biles took a lengthy lay-off from the sport, but is in Paris and already seems back at her best.
On the vault, she executed the Yuchenko double pike – the first time a woman has ever done that particular move at the Olympics.
It is the hardest difficulty move on that apparatus.
She took a slight step back, but managed a score of 15.800. That was comfortably the leading score.
Fans were mesmerised on social media, with one writing: “Simone Biles creating history ….hell rewriting history.”
Another added: “What a ridiculous athlete.”
