RUNNING machine Stefan Giro has established himself as Fremantle's new time trial king, pipping wingman Bradley Hill in the 2km race at Victor George Kailis Oval on Wednesday.

It's back-to-back wins for Giro after the 19-year-old won the race among the first-to-fourth-year players a fortnight ago.

Impressive young midfielder Andrew Brayshaw finished third in the latest edition, backing up from his second-place result a couple of weeks ago. 

Defender Ethan Hughes and wingman Ed Langdon were fourth and fifth respectively.

Giro takes over as the Dockers' running maestro from Tommy Sheridan, who joined Greater Western Sydney as a delisted free agent.

In 2016, Hill was the time trial champion.

Giro said having the form Hawk behind him spurred the South Australian along.

"It helps having Bradley behind me, just pushing me the whole way," Giro told fremantlefc.com.au. 

"I could hear him the whole time so it was good to have him as motivation and to finish in front."

Brayshaw wasn't expecting to run when he got to the club in the morning.

"I came in today not thinking I was doing the run and then we were all told we were re-running it," Brayshaw said. 

"It's not a lot but in two weeks you can build up a fitness base and I'm happy to shave off that one second.

"It's really pleasing. I was just talking to Stef before, he said he was really excited and happy to have a good run.

"I'm really happy for him and it's good to see the first-to-four-year guys are all fit and run really well today."
