A Sydney cyclist is appealing for information after he was struck by a van in an alleged hit-and-run on Friday morning.

Eddie Vining was training with a group of triathletes in Centennial Parklands at about 7:00am when a white van reversed out of a parking space and into a small number of cyclists.

The van hit Mr Vining, leaving with him a broken collarbone, ruptured ligaments and a deep cut on his forehead, before driving off.

Mr Vining had to have surgery for a broken collarbone following the accident.

"The van stopped for a moment so we thought the driver would get out, but then they drove off," Mr Vining said.

"Everyone else managed to move out of the way before the van came out.

"No one got a look at the license plate because they were helping me off the road."

The cyclist was taken to hospital by ambulance where he was cleared of any serious injury. He underwent surgery for his collarbone on Saturday.

"I've left the hospital now, the doctor said everything went fine," Mr Vining said.

Driver got out and looked at victim before driving off

Mr Vining's coach, Dani Andres, said the cyclists were riding around centennial park when the van pulled out of the parking spot "without looking".

Mr Andres said the female driver reportedly got out of the vehicle, "looked at Eddie on the ground" before getting back into the van and driving off.

Mr Andres said the act was "appalling".

"I can't understand why she wouldn't help after realising she'd hit somebody," he said.

"We're really lucky Eddie walked away with his injuries and not anything more serious," he said.

Mr Andres, who trains the Pulse Performance group at Centennial Park, is hoping someone in the area caught the driver on dashcam footage.

The white van has yet to be identified but Mr Vining said he would be filing a police report.
