Gold medal favourite and world No.1 Fox added a bronze to the silver medal she won at the London Games.

Fox (102.49) had a two-second penalty in her final run with two gates remaining and finished behind London bronze medallist Maialen Chourraut (98.65) of Spain and New Zealand's Luuka Jones (101.82) at the Whitewater Stadium in Deodoro.

"The only one missing now is the gold medal and I'm more motivated than ever," she said. "The lead-up to Rio, there has been a lot more expectation and lot more pressure but that's something that I've taken in my stride.

"I've had expectations on myself and I wanted to win that gold medal."

The Australian was sixth away in the final and hit the lead with four paddlers remaining, only to cop a penalty after a video review which eventually cost her a silver medal.

Chourraut blitzed the course in very windy conditions and Fox admitted there was nothing she could do on the day to stop the Spaniard.

"I'm thrilled for her, she really paddled well today. I don't think I rivalled her today, she was incredible and I'm so happy for her and to be on the podium next to her," she said.

Fox had no issues with the call judges made after they ruled she touched gate 22.

"With the wind it was hard to know but with the video I'm sure it was probably there," Fox said.
