Izzy Flint claimed two under-23 national titles and Cam Ivory one while Scott Bowden and Daniel Aurik picked up silver medals at Awaba Mountain Bike Park in NSW.

Launceston's defending champion Sam Fox set a ferocious tempo from the start of the short-track events..

As Fox looked to accelerate to keep control of the race, he suffered a collision and slipped back allowing Dan McConnell to hit the front with three laps to go.

Canberra's 38-year-old multiple Olympian staved off all challengers to win his first national championship since 2021, producing a tight sprint finish to edge out Hobart's Rio Olympian Bowden who recorded the same time.

Fox was two seconds back in fourth.

Flint won the under-23 title by 16 seconds and Launceston Mountain Bike Club teammate Aurik came second in the under-23 men, 41 seconds behind Queensland winner Joel Dodds.

Although Fox relinquished his national jersey in the cross-country races, the tiel stayed in Launceston with Ivory taking the win on Sunday. Fox again finished fourth and Bowden was sixth.

Flint backed up with her second under-23 title, winning by a huge margin of 12:46.

Aurik again finished second to Dodds in the under-23 men's race.
