Incredible Biles continues golden run at World Championships

American Olympic champion Simone Biles, already the winner of more world championship gold medals than any other gymnast, closed out the 2018 championships with two more medals, including a gold, at Doha on Saturday.

Biles pushed her all-time gold medal haul at world championships to a record 14 when she claimed top honours in the floor exercise for her fourth gold in Doha.

The 21-year-old also added a bronze on the balance beam to earn her sixth medal this week, the first time since 1987

that a woman has medalled in every event at a world championships.

With 20 overall medals, Biles tied Russia's Svetlana Khorkina for the most by a female gymnast in world championships competition.

Despite suffering kidney stone problems that briefly sent her to a Doha hospital emergency room before the championships, Biles won gold in the team final, all-around, vault and floor exercise, a silver on uneven bars and bronze on balance beam.

Her all-around world title was her fourth, also a record.
