Simone Biles is set to return to competition at the Olympic Games for the closing women’s gymnastics beam final today. The US superstar’s name was included on the list of eight finalists for the beam released on Monday. Biles, the four-time Olympic champion widely considered to have pushed the sport to new limits, has said she is struggling with the “twisties”, a condition where gymnasts lose the ability to orientate themselves in mid-air. She dramatically pulled out of last week’s opening team competition after one vault, and subsequently withdrew from the all-around final and three of the four apparatus finals — the floor, vault and uneven bars.
