A minute's silence will be held on Sunday morning before the start of the elite women's road race at the Australian championships.

Brown won the time trial at the national road championships and Chapman was second on Thursday, the first elite cycling event held in Australia since Hoskins' death on the weekend.

"It's been a really dark week," Brown said after her fourth time trial national crown.

"The cycling community is struggling to comprehend it really.

"Personally, I'm just super-sad for Mel and her family, really thinking of them. It's just a shadow over (Australian) the summer of cycling."

Chapman agreed with Brown about remembering Hoskins on Sunday, saying it is "100 per cent necessary."

"It's an absolute tragedy and my heart goes out to Mel's family - with all my heart. It's devastating," said Chapman.

Hoskins' husband, Olympic medallist and former cycling world time trial champion Rohan Dennis, faces charges over her death in Adelaide.

Hoskins was a two-time Olympian on the track and she was a member of the squad that won the 2015 team pursuit world championship.
