Star filly Enable will have her well-being firmly tested on Saturday when she takes on Crystal Ocean in the September Stakes at Kempton Park.
John Gosden's awesome daughter of Nathaniel has not raced since she stormed to victory in the Prix de l'Arc de Triomphe at Chantilly last autumn.
Having previously won the English, Irish and Yorkshire Oaks as well as the King George at Ascot, her Arc victory completed a remarkable Group One five-timer.
Enable was set to start this season in the Coronation Cup at Epsom but a minor leg concern set her back, forcing Gosden to remain patient.
The all-weather Group Three at Kempton over a mile-and-a-half was selected as her comeback target ahead of next month's Arc at the revamped Longchamp.

The presence of Crystal Ocean, last spotted finishing a gallant second to stablemate Poet's Word in the King George at Ascot in July, will ensure a thorough test in the five-runner race for Enable.
With Ryan Moore and William Buick otherwise engaged on a busy Saturday afternoon's racing, David Probert gets the nod from Sir Michael Stoute to partner Crystal Ocean.
He admits that conceding weight to the filly won't come easily, but he is relishing the ride and feels Crystal Ocean can give her a race.
"It's a fantastic ride to pick up, and I can't thank him (Stoute) enough for giving me the opportunity," he said.
"Crystal Ocean is a very nice horse - a top-level performer. He ran a very good race in the King George and has been running consistently well all year.
"We're taking on the filly (Enable), who is getting 8lb, but he has got to have a big chance."
Enable is 8/15 to win the September Stakes at Kempton, while Crystal Ocean can be backed at 6/4.
The star fill meanwhile is 1/1 to grab a second Prix de l'Arc de Triomphe crown in Paris on 7th October.
