While all seven contenders for Sunday’s Group One Prix du Moulin de Longchamp (1,600m) have won at Group level, it will come as a surprise, bordering on a shock, if one of four-year-old grey Charyn or imposing three-year-old chestnut Notable Speech doesn’t snare the spoils.

Charyn is an example of a colt whose three-year-old career gave just a hint of what he could achieve the following season.

He has simply got better and better in 2024, with 1,600m Group One demolition jobs in Royal Ascot’s Queen Anne Stakes and again in last month’s Prix Jacques Le Marois at Deauville.

They both came on a straight track and on fast or good ground, but earlier in the year he won a Group Two at Sandown going around a right-hand bend like ParisLongchamp, and on slow ground.

“He’s an easy horse to deal with and can go in any ground you ask him to,” said jockey Silvestre de Sousa. “It looks like it will be good on Sunday but if it turns softer it won’t matter to him.”

“He is a very genuine horse who gives you 100 per cent each time and I don’t think we have yet got to the bottom of his ability.”

William Buick offers an equally positive judgment about Notable Speech.

Despite an unbeaten history, he was widely ignored as a likely winner of May’s Group One Newmarket Classic – the 2,000 Guineas (1,600m) – but he proved far too strong for subsequent dual Group One winner Rosallion and nine others.

Then came his sole lapse, at Royal Ascot, before bouncing back stylishly with a fluent victory in Goodwood’s Sussex Stakes (1,600m), his second Group One victory in just six career starts.

“He was a brilliant Guineas winner capable of a rare change of gears, and he showed that again at Goodwood,” Buick said.

“His run at Royal Ascot [when seventh in the St James’s Palace Stakes (1,600m)] was simply too bad to be true. He’s such a brilliant horse, a horse that really excites you and it’s a real privilege to be riding him.”

Rounding out the field for the Prix du Moulin de Longchamp, which will be simulcast by the Jockey Club on Sunday night, are Henry Longfellow, Tribalist, Ramadan, Caramelito and Kelina.
