This is it. One last hurrah. And Canberra BMX star Caroline Buchanan hopes it's a case of third time's a charm.
Her entire focus is on qualifying for the Tokyo Olympic Games, which will be her last BMX stand.
The 30-year-old hopes the Games go ahead in Japan in July, as she looks to put double Olympic heartbreak behind her.
She went into London as the No.1 women's rider and Rio de Janeiro as No.2. But didn't come away with a medal.
Buchanan's also put a devastating off-road buggy crash in 2017 - that left her with a broken nose and sternum, and two collapsed lungs - behind her.
The body's fully healed. And now it's all systems go for Tokyo.
"The goal is to obviously go to Tokyo," Buchanan said.
"I've sort of always planned for BMX racing for this to be my last Olympic Games and then to continue with mountain biking and all my other goals within cycling beyond this year.
"Postponing [the Olympics] a year has been really great for me to continue with my training base and build my strength-and-conditioning numbers to where they need to be.
"Now it's just back to as if the Games are going to go ahead and continuing to train towards it."
MORE CANBERRA SPORT
These days Buchanan's based in Canberra, spending more time in her home town than she has in years.
It's even allowed her to get a French bulldog puppy called Kremmo. And she's travelling around the country - when she can - getting ready for a big year ahead.
Her BMX track to Tokyo will go through Germany and Colombia for World Cup events in May. Where she'll look to book her plane ticket to Japan.
"Who knows how that travel schedule is going to look, and quarantine, but at the moment that looks like the road map to the Olympics," she said.
"Hopefully quarantine can look a little bit better in the next few months for athletes returning to Australia who are trying to get these last-minute spots.
"Maybe we'll have a bike or something set up in our room ... but still qualifying rounds ahead and staying accountable towards that goal."
This Olympic preparation has had a different feel to ones in the past. This time she's doing it on her own.
Gone is the backing of AusCycling. And with it the backing of the AIS. And all the bells and whistles that come with it.
So instead the world No.36 been thinking outside the box.
"I've got the president of ACT Powerlifting, Grant Haines, coming out every week to my home gym and helping me train in that weightlifting space," Buchanan said.
"I've been caught in this little bit of a limbo of being in the Olympic long list and being in contention for the Tokyo Games, but outside of the Australian cycling team.
"So I haven't had access to the AIS and some of the facilities I would normally have access to when I've been home in Canberra.
"Fortunately the support network around me is still keeping me on track for Tokyo."
And the injury? The pesky sternum that needed multiple surgeries to get right. That's all long fixed.
She's been back on the bike for a year and a half.
"Within the last 12 months I've been hitting PBs in the gym, back up to 20 watts per kilo," Buchanan said.
"I know my sternum's strong. I've been deadlifting 140kg. No bolts have popped out or no plates have snapped.
"I've given it a good test - something would've gone ding by now."
Buchanan's already helped inspire the next generation of Aussie BMX stars.
But that could be doubled down with the announcement that Brisbane's in the box seat for the 2032 Olympics.
Especially if she goes well in Tokyo.
She was just nine when the Sydney Games were held in 2000. And she felt that home-track advantage could manifest itself into BMX medals.
"It's amazing news for Australia to host an Olympic Games again in 2032," Buchanan said.
"A 32-year gap since the last Olympics where held in Australia in Sydney in 2000.
"It will play a huge advantage for the athletes to compete on home soil and especially BMX athletes to have home-track knowledge.
"We've got some incredible up-and-coming BMX talent here in Australia and an Australian Olympics gives these younger athletes a truly unforgettable experience to aim towards."
