Just a couple of weeks after sharing a world championship madison silver medal, Rio Olympic teammates Amy Cure and Georgia Baker dominated the elite women's 10km scratch race.

In a thrilling sprint finish, Cure, of West Pine, held off a late charge from Baker, of Perth, and their regular team pursuit colleague Ashlee Ankudinoff (NSW) to clinch a third straight title.

Cure made an ambitious breakaway with 15 laps to go of the 40-lap race with Josie Talbot (NSW) and Chloe Moran (SA) before Alex Manly (SA) reeled in the trio.

Cure and Manly went clear before sitting up for the sprint finish.

"It was really good, I was happy to cross the line first but I wasn't sure how I was going to go as I've been a bit sick so I'm really happy with my performance tonight," said Cure, who will look to defend her points race title on Saturday's final day of competition.

And there was a maiden senior national medal for Launceston's Josh Duffy in the elite men's time trial.

Former junior world champion Thomas Cornish (NSW) claimed his maiden elite national title by clocking 1min 1.653secs in the 1km event.

Victorian Godfrey Slattery (1:03.004) squeezed out Duffy (1:03.258) for silver.

The Tasmanian team, which also includes Lauren Perry, Zack Gilmore and Macey Stewart, is being coached by Matthew Gilmore of the TIS.
