This month, not only did Buchanan, an eight-time world champion and two-time Olympian BMX rider, feature on a Nutri-Grain box, she also starred in its Unstoppable advertising campaign.

"I don't know if I manifested it or put it out there but it's random that all of these years later NutriGrain approached me and said they were interested," she says.

"They felt the story that I have with all of my setbacks and adversities and being a world champion at the top of my game and having to start again and show resilience aligned with their Unstoppable mantra."

At the end of 2017, the Canberran almost died after an off-road accident resulted in a crushed sternum, collapsed lungs and dangerous bleeding around her heart.

With multiple surgeries and rehabilitation on the horizon, Buchanan knew that it would be a two-year journey before she could return to the BMX World Cup start gate. She also knew that she had two options: to disappear for a while, or share her recovery. Buchanan chose the latter.

"I'm glad that I put it out there but I think at the same time it took a lot of strength to show all of those surgeries and those gruesome photos," she says.

"The majority of my life I've shown through social media the highlights story - the podiums and the race wins and everything was very glittery. To show the real raw truths about some of the hardships that I went through, I really feel like it's been helpful in a time where my identity as an athlete was stripped away from me."

It was, of course, this unstoppable story which saw Nutri-Grain ask Buchanan to be a part of its Unstoppable campaign.

Along with fellow BMX rider Rhys Kember, Buchanan spent three nights in Sydney filming the TV commercial, which featured a BMX playground made out of a giant cereal bowl and Nutri-Grain box.

"The kind of whole TV story was me and Rhys Kember, and we're sort of battling head to head," Buchanan says.

"We come together at the end with our Nutri-Grain it reveals me as being a girl and that was another aspect. They wanted to showcase a girl for her sporting abilities, so there was that reveal at the end."

The next few months are going to be busy for Buchanan, who is back on the World Cup tour and has seven more qualifiers between now and the Tokyo Olympic Games.

"I'm only one race in so far. Shepparton was the first round of the World Cup tour, so luckily it was on the home soil in Australia," she says.

"I got into the quarterfinal the first day, semi-final the second day and my next World Cup will be in Manchester so I'm hoping to take that one step further to the final and just keep progressing."
