Art Sherman admits California Chrome could be facing his toughest test yet as he gears up for Wednesday's Prince Of Wales's Stakes at Royal Ascot.
Winner of the Kentucky Derby and Preakness Stakes last term, California Chrome was last seen when finishing second to Prince Bishop in the Dubai World Cup at Meydan in March.
The four-year-old has been lodging with Rae Guest in Newmarket for the last couple of months, but trainer Sherman and part-owner Steve Coburn have now arrived in preparation for next week's Royal meeting.
The pair were on hand as California Chrome enjoyed a routine spin on the Watered Gallop in Newmarket, with big-race rider William Buick in the plate as the duo finished comfortably clear of a lead horse.
Sherman said: "He looked good and he was impressive the way he finished up the hill. This is all a totally new experience for him, but I'm sure he will be fine as he's a smart horse.
"He has run on the grass before but it was completely different to what he will face at Ascot.
"He looks good and he looks fit. My son said he worked really nicely down at Ascot last week.
"I think it's the biggest challenge he's faced so far as there are some great horses in the race, but I don't see him being that far off."
