The medal haul keeps Fox among the favourites as she looks to add to her silver won in London in 2012 and bronze from the Rio Olympics.

In her only international racing ahead of the Games due to COVID-19 disruptions, Fox won gold in the women's K1 (kayak) at the second ICF Canoe Slalom World Cup in Leipzig. She also finished fourth in the C1 (canoe).

That came after a gold medal in the C1 and K1 bronze a week earlier in the World Cup in Prague.

While disappointed to miss a C1 medal in Germany, after winning four world titles in the discipline, Fox said she took some risks which didn't really pay off.

Germany's reigning world champion Andrea Herzog won the event, turning the tables after Fox's success in Prague.

"I tried to push the boundaries, cut the lines a little bit, changed my tactics," Fox said.

"Some of it paid off, but two big mistakes meant that it's fourth place. Andrea (Herzog) put down an amazing time to start with and I was really hoping to chase that but it wasn't the run I was hoping for in the final."

But 27-year-old Fox could still celebrate her K1 victory, finishing an impressive 3.52 seconds ahead of German duo Ricarda Funk and Elena Apel.

She felt in good shape ahead of Tokyo, where women's will contest the C1 for the first time.

"Overall there has been really good paddling and I'm really pleased with the way I've raced and there have been good runs across the board so I've got a lot to take away and work with," Fox added.

In the men's events, Tasmanian Daniel Watkins, who will make his Olympic debut in Tokyo, bettered his result in the men's C1 from the first World Cup by three spots to finish 17th overall in Germany.

Tokyo teammate and Rio Olympian Lucien Delfour said he had a "shocker" in Germany, although drew confidence from his 13th placing in Prague.

Australia's Olympic paddlers will train in Europe over the next few weeks, before heading to Tokyo at the start of July for an ICF training camp on the Olympic course.
