Few athletes were more hyped at the 2021 Olympics Games than Simone Biles, the world champion who's taken gymnastics by storm.
And while Biles still went home from Tokyo with a silver and a bronze medal, she pulled out of a number of her most hyped events, citing the need to care for her mental health.
It sparked intense interest and now a new documentary promises to give a peek at her innermost thoughts during the Games.
What happened to Simone Biles at the Olympics?
Ahead of the Games, there was speculation Biles could take home multiple gold medals as the undisputed GOAT of gymnastics.
But when competition came, she took time out, withdrawing from some events and saying she needed to put her mental health first.
"We have to protect our minds and our bodies and not just go out and do what the world wants us to do," she said at the time.
Biles later said that in the run-up to the finals she had experienced the dangerous sensation known as "the twisties" — where she became disoriented mid-air.
But we're about to learn more about what went on behind the scenes, with the new episodes of Simone vs Herself.
How can I watch Simone vs Herself?
Simone vs Herself has actually already been released on Facebook Watch, however, that was before the saga at the Olympics.
The Emmy-award winning "versus" series released five episodes featuring Biles in the lead-up to the Games.
Now a two-part season finale will be released on Facebook Watch, chronicling the gymnast's time in Tokyo.
Two episodes will be released, one at 2:00am Tuesday Australian time, and the following at 2:00am the day after.
Other episodes of Simone Vs Herself have featured exclusive interviews with Biles and the trailer for the show's return teased more of the same.
"I'm having these mental blocks in the gym recently, it's not been fun, it's been scary," it shows Biles saying in a video diary.
"I'm getting lost in my skills … it's getting to the point where it's becoming dangerous."
Biles has promoted the documentary on Instagram, describing it as "my story in my words".
What is Facebook Watch?
It's Facebook's on-demand video platform, and the Versus series is one of its most popular programs.
It's free to watch but is supported by advertising.
The Versus series has previously looked at other greats of US sport, with Tom [Brady] vs Time and Stephen [Curry] vs The Game.
The latter won an Emmy in 2019 for best serialised sports documentary.
