Gilmore is one of six cyclists aiming to secure a spot in Australia's three-person road race team.

The Commonwealth Games gold medallist will leave her Cronulla home to race in Belgium on February 25.

The Johnny Warren Jamberoo Classic is a 100-kilometre charity ride from Loftus Oval to Jamberoo in honour of the late football legend.

"I've wanted to do it since the first time I rode it but I haven't been able to because of my schedule," Gilmore said.

"I'm happy to have a hard ride or an easy ride because I'm coming off the end of a large training block.

"I'll find a group and see how I go.

"If they want to go hard I'll go with them."

The past couple of months have been challenging for Gilmore as she tries to get her Olympic dream back on track.

Six months ago a bad fall resulted in multiple breaks in her pelvis, a back fracture and cracked ribs.

"I've been injury-free since November and my body has coped with the heaviest training load I've ever put it under," Gilmore told the Leader.

"So I'm quite happy."

Between now and when the Olympic team is picked in June, Gilmore will race 20 times.

"I won't go four or five days without racing," Gilmore said.

"There's a lot of travelling: 15 countries."

Gilmore will spend the rest of the season at her European base in northern Italy.

The Johnny Warren Jamberoo Classic raises money for the Sydney Cancer Centre at Royal Prince Alfred Hospital.
