Australian cyclist Anna Meares will become the most successful female in UCI Track World Championships history if she can claim gold in France this week.
Meares has won 10 world titles in 11 appearances at the world championships and an 11th gold medal in Saint-Quentin-en-Yvelines will see the 31-year-old move clear of former French cyclist Felicia Ballanger.
Last year, Meares claimed silver in the 500m time trial and keirin and she is much more confident in 2015.
The veteran, who has also won two Olympic gold medals in her career, is expected to race in those aforementioned events, plus the individual and team sprints just outside Paris.
"I am in a very different place now than 12 months ago, I am much more content with my preparation and my goals," she told Cycling Australia's website.
"And I know that this race will be better than my last. My goal is all about [the Olympic Games in] Rio [de Janeiro] in 2016 and these World Championships will be a huge step to prepare me for that."
Meares is one of three Australian women selected for the sprint events.
Her three-time world champion team-mate in the team sprint - Kaarle McCulloch - has also been picked alongside Stephanie Morton.
In the men's sprint events, Francois Pervis will look to defend three titles in front of his home crowd.
The 30-year-old Frenchman won the sprint, one kilometre time trial and keirin in Cali, Colombia, in 2014.
But Great Britain's Jason Kenny is targeting Pervis with the 2012 Olympic sprint champion having lost to the latter in the quarter-finals in Cali.
"I've got a lot of medals but not a lot of them are gold at a World Championships," Kenny told British Cycling's website.
"I've only got two golds so it would be nice to kind of stick a few more in there."
In the endurance races, Great Britain will look to defend the women's team pursuit and individual pursuit, while Australia are in the same position for the men.
Alex Edmondson won the individual title for Australia and was part of the quartet that claimed the team event as well, and the 21-year-old is expected to hit the boards in both races again in France this year.
Germany and France dominated last year's world track titles with four gold medals each, while Australia (three gold) matched the Germans with eight total medals.
