Aussie Olympics hero reacts to woke vegetarian, no-alcohol Games in Paris by necking a beer and eating her favourite Macca's meal

Aussie BMX star Natalya Diehm has become an instant sporting cult hero after skolling a beer and enjoying some McDonald's chicken nuggets following her bronze medal in Paris.

Diehm, 26, has overcome five knee reconstructions in what has been a stop-start career on two wheels - not to mention dislocated shoulders, broken wrists and elbows.

In one of the feelgood stories of the Games, persistence paid off for Diehm when she made history as the first Australian woman to win a BMX freestyle medal in any major competition.

And when offered a beer by reporters, the Queenslander celebrated accordingly - while fans at Olympic venues are unable to get any alcohol.

'I'm not a beer drinker, but I'll do it for everyone,' she said amongst a chorus of cheers from journalists.

'I thought about doing a shoey.. but that's probably not appropriate.'

Diehm also confirmed that, like many athletes, she has found the food options in the Olympic village frustrating as the Games switched to a far more heavily vegetarian range of options for competitors.

'I do not want to go back and eat that [vegan options] again. I'm stoked with my Macca's,' she said.

Diehm's honesty comes as alcohol has been scarce at many Olympic events in Paris, with a push for a family-friendly Games by organisers.

Multiple 'dry' venues have bemused many supporters, who have resorted to drinking at bars across the capital pre and post events. 

Meanwhile, when it came to her dynamic performance at the La Concorde skate park, Diehm was elated at creating her own slice of history.

'We've [Australia] never medalled at a World Cup event at all,' she said.

'So to do it here on the biggest world stage, that's going down in history. I've written history. That's insane. 

'I look at it [bronze medal] as a rose gold. It's beautiful, I think it's even better than the gold, I'm not going to lie.'

China's Yawen Deng (92.60) won gold in the women's BMX final from American Perris Benegas (90.70).

Tokyo gold medallist and fellow Aussie Logan Martin put aside his personal disappointment at missing out on back-to-back titles to celebrate Diehm's triumph.

'It's awesome what she's done,' he said.

'She's just wanted to make a podium — and she's made the biggest one ever. For her to now have an Olympic medal, I'm super proud of her.'
