COPENHAGEN: Cameron Meyer added to Australia's early gold rush at the world track cycling championships on Wednesday, but this time had the bonus of posing in the rainbow jersey with Anna Meares.

Meares helped ease the pain of recent deaths in her family by reclaiming the 500 metre time trial crown to add to her titles in the event from 2004 and 2007 with a superb personal best of 33.381sec.

Defending champion and reigning world record holder Simona Krupeckaite of Lithuania, who beat Meares to the gold last year, finished second in 33.462, with Olga Panarina of Belarus winning bronze in 33.779.

Coming only days after the death of two close family members, her grandmother and her husband's grandfather, Meares' achievement was an emotional one.

But despite having a tear in her eye, the 27-year-old from Queensland admitted she has positive thoughts ahead of more difficult bids for silverware in the team sprint, keirin and sprint events.

"When I crossed the line and saw the 33.3 I thought it was a great time, but I wasn't sure that was going to win it," said Meares. "It was so tight, right down to the line but I'm so pleased that I've won this.

"My Nan passed away two weeks ago and my husband's grandfather passed away two days ago, so I had a bit of extra spirit on my shoulders tonight.

"To come away with such a good performance, I'm so happy."

Meyer then produced a points race masterclass to successfully defend his crown from last year, lapping the field twice to finish on an impressive total of 70.

His nearest challenger was Dutchman Peter Schep on a distant 33 with Milan Kadlec of the Czech Republic winning the bronze on 27.

Meyer, who is in his first year as a professional with Garmin's road team, still has the team pursuit event and the Madison to come.

The 22-year-old Western Australian admitted he was determined to go out and win so he could pose alongside Meares, this time with both of them in their rainbow jerseys.

"Last year (when Meares won silver) we had some nice photos together, but we said it would be nice to have photos of us both in the rainbow jersey," he said.

"It was pretty inspirational seeing Anna win the 500 metres so I was pretty determined to go out there and win."

Meyer never gave his rivals a chance in the 160-lap epic, in which he virtually secured victory after lapping the field twice after the eighth and 12th of the race's 16 sprints - a feat rewarded with 20 points.

"I had very good form going into the race and also that I was going to be one of the strongest out there in the second half of the race," he added.

"But my coach was standing at trackside and telling me the rest of the field were getting tired. After that it was a case of keeping calm, controlling my breathing and just trying to control from the front.

"I'm so happy to be the world champion again."

The only negative point for Australia was their men's seventh place finish in the men's team sprint, in which Germany beat four-time defending champions France.
