Australia's Lachie Lansdown and Jordan Mercer and New Zealand's Annabel Anderson all secured their second gold medals of the International Surfing Association (ISA) World Stand Up Paddle (SUP) and Paddleboard Championship in Vorupør.

Lansdown and Mercer took gold in the men's and women's paddleboard technical races respectively, while Anderson topped the podium in the women's SUP technical event.

The other title decided today in Vorupør, nicknamed "Cold Hawaii", went to Hawaii's Mo Freitas.

Freitas claimed the men's SUP technical race crown to clinch his maiden ISA gold medal.

Lansdown triumphed in the men's paddleboard technical race in a time of 21min 54.94sec, beating Sam Shergold of New Zealand, who earned the silver medal.

The bronze was sealed by Julien Lalanne of France.

Mercer continued the Australian charge as the most decorated ISA athlete of all-time powered to her 10th individual title in 23:07:14.

Jasmine Smith of New Zealand did enough for silver, while Denmark's Kathrine Zink came through to take bronze.

The results for the Australian duo saw them add to their distance race gold medals in Copenhagen last weekend.

Mercer’s success is remarkable as it has come just days after the death of her uncle Dean, a renowned competitor in surf livesaving, who she dedicated her first world title to a week ago.

He had died of a heart attack at the age of 47 while driving on the Gold Coast.

"To be out there healthy and feeling fit is incredible," said Mercer. 

"To be back racing and able to go as fast as I want to go is something that I really missed this past year with injures.

"Today I had the opportunity to defend my title, but more importantly to inspire my team-mates. 

"We are just over the halfway mark really and this is when the points start to count."

Anderson, who won the SUP distance title, was in dominant form once again as she surged to technical race glory by clocking 21:10.17.

Olivia Piana of France earned the silver medal and Australian Terrene Black claimed bronze.

Freitas recovered from a tough start in the men's SUP technical event on his way to clinching his first-ever gold medal at this level.

He finished in 19:19.44 to lead home a Hawaiian one-two as team-mate Connor Baxter was narrowly adrift in second, crossing the line 0.20 seconds behind.

Danish legend Casper Steinfath won the bronze medal.

The event is due to conclude tomorrow with the relay and Closing Ceremony.
