Dryden's hoping for a place in a tough Doncaster Prelude (1500 metres) as he wants to see whether the son of Star Witness can run a mile.

He'll wait to see what champion jockey Glen Boss thinks after the group 3 race at Rosehill on Saturday - which will be the first time Handle The Truth's raced further than 1400m.

The five-year-old has freshened up since his win in the listed National Sprint (1400m) at Canberra one month ago, with the Brisbane winter carnival a possibility later in the year.

"He's not nominated for the Doncaster. Say he won and there was a late-entry fee I spose you'd look at it," Dryden said.

"The plan would be maybe one more run to the paddock, a little ease up and then maybe look at going up to Brisbane over the carnival there.

"But we'll make that decision after [Saturday]."

Dryden had also looked at the group 3 Star Kingdom Stakes (1200m) as a possibility, but felt dropping back in distance might be a tough ask.

He felt a good showing in the Prelude would show he could handle the longer trip, which in turn would open a few more doors for the gelding.

"He's going well. It's a big step-up in class this time. But I've always wanted to try him over a mile," Dryden said.

"I didn't really want to drop back to 1200m in the Star Kingdom [Stakes].

"The Star Kingdom was probably an easier race, but I think he's more suited by the longer distance. He seems a bit more dour in his work.

"I've always thought he could run a mile so [Saturday] we'll find out if he can run a reasonable race.

"It broadens our horizons a little bit, but a very tough race. If he can run a place it would be a great result for us."
