The 24-year-old started the year off with a bang in June and continued that form through until the Canoe Slalom World Championships in Brazil last month. 

It's been a couple of weeks since the season finished and Fox has since returned back home to Australia with her achievements starting to sink in. 

"It's kind of sunk in what's happening and what I've achieved," she said.

"It's just been an incredible year, I never would have imagined it at the start of the season and it's very special to now be home and be able to share it with everyone and kind of reflect on what a massive year it's been.

"At the same time, I'm kind of sad that it's all over and I'm going to wait until next year to get back overseas and race again," Fox said.

Heading into the season, she knew that she would be able to defend her 2017 K1 World title and had a goal to win an overall World Cup title for the same event, something she had never achieved before. 

Fox had momentum, winning back-to-back World Cups to start the season and from a far it looked like she was unstoppable. 

"I was like, I'm not stopping, let's see how long I could go and I knew it was possible, but I didn't expect it in that way," she said.

"When I look back now, I prepared extremely well over the summer, physically, mentally and I turned up excited to race. It just felt great and I enjoyed it. I think that's, that always makes a big difference," Fox said. 

She would go on to be undefeated in the C1 event but unfortunately, a bit of momentum was lost in K1 at the back end of the World Cup having just missed out on gold in the fourth meet before finishing 10th in the final World Cup of the season. 

However, despite the little bump, she won both World Cup titles which came with No.1 world rankings in each discipline. 

All her hard work during the season accumulated as the World Championship in Rio de Janeiro, at the same course she had raced two years prior. Fox was set to win an Olympic silver medal in the K1 but a time penalty for touching a gate saw her take bronze.

She exercised her demons in Rio, showing her experience and grace on the water in the K1 final to beat British paddler Mallory Franklin. 

Unfortunately, she couldn't enjoy her K1 win. 

The program had changed previous World Championships, where they would perform one event per day but this year Fox raced the final of the K1 on Saturday morning then had to do the C1 semi-finals in the afternoon. 

"So I won the title for K1 in the morning and that was like a massive deal to me, and I couldn't really appreciate it," she said.

"I had to get ready to race in C1 that afternoon, I had drug test between and it was sort of like I had to just move on very quickly and that kind of sucked because I just achieved this awesome thing and I couldn't enjoy it," Fox said.

So when she crossed the line knowing she had won the C1 gold, all her emotions poured out.

"It was just unbelievable. I couldn't believe that I'd managed to back it up. I managed to win another world title and I'd managed to win the double again, all that emotion came out," she said.

"It was a weird feeling to just let it all out when I've been holding it in."

It is the second time the dual Olympian had won both the C1 and K1 titles, with the first being in 2014. The win also meant that she had gone through the season undefeated in the C1.

It was also a family affair with Fox beating her father, Richard, who won five individual titles, as she became the most successful individual paddler in history before leapfrogging her mother, Myriam Jersusalmi, to become the most successful female paddler in history.

"It was never something we talked about and I was never really aware these records," she said.

"I only became aware that when a journalist told me after I qualified in the K1, and he said, 'Oh, do you know that if you would want world title, you'll overtake your dad and if you win two world titles you'll overtake your mum?'.

"I was like I just made the final so I'm going to race and we'll see what happens.

"To actually achieve that and be called the greatest of all time, in my in my sport, it's kind of something I never would have thought would happen," Fox said. 

Attention will turn to next season after a small break with Tokyo 2020 less than two years away. The World Championships next year will act as the first step in the qualification process for the Olympics where paddlers will be looking to qualify a quota spot for Australia before the internal selection process in January-February 2020.

While the dual Olympian says there is pressure to win a spot on the team, it normal to feel being an athlete.

"I think that's normal for any athlete and in any sport and I've come to accept that and take it on board," Fox said.

"There is pressure because only one person can qualify in each event, which makes it really tough because in other sports there is a lot more per event or per country."

Tokyo 2020 will be the first time C1 is offered to female paddlers with Fox hoping to qualify in both the C1 and K1 events. However, despite having a standout season, she knows it doesn't guarantee her a spot.

"I know that even though I've had this success this year it doesn't guarantee me going to Tokyo and so I've got to be prepared for those trials and ready to race for my place," she said.

The 2019 Canoe Slalom World Cup season begins on June 14 in England.
