Having already retained the keirin title, Francois Pervis continued to delight the home crowd at the UCI Track Cycling World Championships by defending his kilometre crown.

Pervis has been in fine form of late and recorded a time of one minute 00.207 seconds to finish clear of Germany's Joachim Eilers and New Zealand's Matthew Archibald.

With the sprint event to come later this weekend, Pervis remains focused on adding another medal to his haul in Paris.

"In the sprint tournament, I will have the crowd behind me, it will make the difference as it did today," he told Direct Velo.

"It is a difficult challenge but no challenge is easy. I believe in my chances. I have nothing to lose and I've had the taste of winning. I will try to do it with pleasure, this is the only way to succeed."

Elsewhere, Fernando Gaviria leads the men's omnium competition following the first three tests, having finished in the top three in each with Elia Viviani and Thomas Boudat trail him going into Saturday's final.

Australia's Rebecca Wiasak recorded a surprise win in the individual pursuit as she picked up a gold medal on her first appearance at the competition.

Her time of three minutes 30.305secs was enough to finish clear of American Jennifer Valente while Russian Artur Eschow was the winner in the men's points race.

World champion Kristina Vogel remains on course to defend her sprint title after making it to the semi-finals thanks partly to a victory over perennial runner-up Simona Krupeckaite.
