Simone Biles defied a kidney stone to become the first female gymnast to win four all-around world titles, on this day in 2018.

Such was the American’s dominance of her sport, she could afford a series of uncharacteristic mistakes in Doha without feeling unduly threatened by her rivals, with Japan’s Mai Murakami taking silver more than one and a half points behind.

Victory gave Biles her 12th world gold medal and her second of the championships. She went on to collect six in total – four golds, one silver and one bronze.

However, after claiming the all-around title, she insisted: “I’m definitely more upset with myself than happy. It’s not who I am go out and bomb a meet like that.

“Even though I still won, I wish it had been something different. It kind of sucks that I did so bad and still won. You have to earn it and I don’t think I earned it tonight.”

Biles’ success was all the more remarkable given her admission to hospital the night before the qualifying round, but she refused to use her continuing discomfort as any kind of excuse.

“If it had been a challenge for me, I wouldn’t have competed at all, rather than blame it on the kidney stone,” Biles added.

“I think finals will definitely cheer me up because I get to redeem myself and show people who I really am.”

Biles took a two-year break from competition following the Tokyo Olympics, during which time she announced she would be working on her mental health and also gave evidence to Congress over the abuse she suffered at the hands of disgraced doctor Larry Nassar.
