Richard Fahey feels Garswood's relaxed style of racing will give him every chance of staying a mile in the Qipco 2000 Guineas at Newmarket on Saturday.
The son of Dutch Art emerged as a live outsider for the colts' Classic when winning the Free Handicap in good style on his reappearance two weeks ago and that seven-furlong contest was the first time he had tackled in a trip in excess of six furlongs.
"You are never confident (about staying) until you have a go, but he's a very relaxed horse now.
“We've kept him relaxed this year and he looks like he'll get it but we'll see," the North Yorkshire handler told At The Races.
"He'd go on any ground, but like most trainers we don't want it extreme. We don't want it very firm and we don't want it very heavy. Other than that, any ground will be OK by me.
"It's fantastic for everybody and we're all excited. A few of the lads in the yard have backed him at 200-1. It's great for us to have a live outsider in a Classic."
Tony Hamilton, who has ridden Garswood in four of his five starts, will have his first mount in a Classic and Fahey stressed that was always going to be the case.
"Tony (Hamilton) has got great belief in the horse and has ridden him in all his work and has ridden him in all his races bar one. It was never in question he would ride him in the Guineas," he said.
