Police have appealed for the driver who hit triple junior world champion cyclist Macey Stewart on Thursday and fled the scene to turn himself in.

The Tasmanian cyclist was nursing injuries as she left for a training camp in Adelaide this morning but said she was happy to be still able to train.

The 18-year-old athlete was training in Devonport when she was hit by a car from behind.

Police later found the car but had been unable to locate the driver, despite an appeal for anyone with information to come forward.

Investigating officer Dean Wotherspoon said the response to the appeal was "fantastic".

"We had a number of people come forward with information about what they saw," he said.

"As a result of this information we've got a specific line of enquiry that we're looking into."

Constable Wotherspoon appealed directly to the driver, urging him to turn himself in.

World Champion cyclist Macey Stewart departs for training in Adelaide a day after she was injured in a hit and run incident.

"The best thing for the driver to do would be to come forward to police," he said.

Stewart used her Instagram page to tell her followers she was alright.

"Off again on my next big adventure!" she wrote.

"Quite sore this morning but it will take more than that to stop me. Watch out Radelaide."

Yesterday she posted a pic of herself on Instagram in a neck brace and being attended to by ambulance officers.

"The driver did a runner after stopping to pick up his mirror that I had broken off while I scrambled to the side of the road to avoid being hit by an oncoming truck," she wrote.

"Macey caught her flight this morning to the Australian Institute of Sport in Adelaide as planned," said Constable Wotherspoon.

"She's feeling bruised and sore but otherwise she is ok," Constable Wotherspoon said.

Anyone with further information is asked to contact police.
