Less than a month after his exit at Fremantle, Tommy Sheridan has made a giant impression at his new home of GWS.

The gun runner proved too strong for his younger teammates, upstaging the club’s first-to-fourth year players to take out the 2km time trial on his first day at training.

It marked a promising start for the 25-year-old at his new club after being delisted by the Dockers following an 81-game stint.

“I just went as hard as I could. I’m feeling a little sick from the run, to be honest,” Sheridan told the Giants website.

“Everyone ran really, really well. It was a strong performance which means they’ve all done work over the off-season and we can crack into some footy.”

Sheridan said his new start at GWS felt like his “first day of school” but praised his teammates for making him feel welcome.

WA product Zac Langdon finished fourth in the time trial as he looks to build on a promising debut campaign at AFL level, where he booted 21 goals in as many games.
