Australian canoeing champion Jess Fox admitted she 'threw up' behind a tent just minutes before storming to Olympic victory with her first gold medal.
Fox finally broken through for Olympic gold after a succession of minor medals by taking out the C1 canoe slalom on Thursday.
The 27-year-old had taken a silver and two bronze medals across the 2012, 2016 and now 2020 Games but got that elusive goal with a flawless, no-penalty time of 105.04 seconds in the final.
But nerves threatened to get the best of Fox before the event, admitting the last thing she said to her mother before the race was that she'd been sick behind some tents.

'I was like, "I feel really good, but I just threw up, so I’ll be alright'. And then we fist bumped,' she said after the race.
'Whatever I‘d had between the runs didn’t sit well and then I just thought, "OK, my body’s ready, that’s just my body telling me to get ready for something big".
'So it’s always about re-framing those things and putting it into a positive.'
Her win brought tears of joy to dad Richard who struggled to compose himself while commentating on the event.
Richard, who was one of the world's top canoeists when he represented Great Britain through the 1980s and 1990s, remained composed while calling the action for Channel 7 but ultimately the emotion got the better of him.
He managed to muster a 'wow' and wiped away tears as he described his daughter's performance as beautiful.
'I love you, I love you, through the finish and beyond the finish, that was amazing. I was crying too,' he told her live on air after the medal ceremony.
Fox replied: 'I love you too. I can't hear everything but, thank you for all the love, the support, the messages.
'I can't wait to show you this one dad!'
Her dad celebrated the victory with a glass of champagne in the studio, toasting a gold medal that seemed to have slipped through Jessica's fingers when she took bronze in an error-riddled performance the K1 final on Tuesday.

'It's unbelievable,' Richard said.
'It's the C1 event, the first time in the Games. It's the race she had to win.
'But, like, so many reasons....and the pressure - we talk about pressure.
'What happened in the K1 final shattered her. To come back from that to recompose herself -she wasn't at her best in the heats - that was so good.'
He later admitted his emotions got the better of him.
'Look, I had a little cry, I will be honest.
'I was quiet. I was just stunned and amazed because you just don't know what's going to unfold.
