After winning 800m and 1500m freestyle gold at Tokyo 2020, Ledecky set her record as the joint most successful female swimmer in Olympic history with five individual gold medals. Her medal tally equals Hungarian legend Krisztina Egerszegi. Only Michael Phelps has won more solo events in the pool – 13.

Simone Biles withdraws from vault and uneven bars

Gymnastics legend Simone Biles has put her Olympics in doubt after withdrawing from the vault and uneven bars finals tomorrow.

The 24-year-old, a four-time Olympic champion, pulled out of the artistic gymnastics team and individual all-around events last week to "focus on her mental health." Biles later revealed she had the "twisties", a mental block sometimes suffered by gymnasts.

The American is yet to decide if she will compete in the floor on Monday and balance beam on Tuesday.
