Newmarket trainer John Gosden has admitted Saturday’s Coral-Eclipse will provide the toughest test so far for Golden Horn.
The three-year-old thoroughbred has won all four of his races since his debut in October, the latest of them being a thrilling victory in the Epsom Derby last month.
However, Gosden believes this weekend’s Group One race, which is part of the lucrative British Champions Series, will be the biggest challenge of his unbeaten runner’s career so far.
“It’s going to be an intriguing race,” said Gosden, who enjoyed success in the Irish Derby at the weekend with Jack Hobbs.
“He’s taking on the crème de la crème. The Grey Gatsby is a winner of many Group One races and has won over two million pounds in prize money.
“It’s a small field he’s up against, but we’re happy with how he’s been since the Derby. He’s ready to race.”
A win at Sandown Park on Saturday (3.45pm) would see Golden Horn’s earnings tip over the million pounds mark, with the bookmakers having priced him as the red-hot favourite at 4/11.
The Grey Gatsby is second favourite at 7/2, with Gosden’s other runner, Western Hymn, and Aidan O’Brien’s Cougar Mountain both available at 10/1.
French Derby winner New Bay was the notable runner ruled out of the race, as the five-day declaration stage on Monday saw the number of entrants cut from 30 to just five.
