Five juveniles who can add another chapter to remarkable story

Frankel has made a phenomenal start to his stud career with 15 winners already on the board and nine individual winners from just 13 of his offspring who have hit the racecourse. Our Newmarket correspondent David Milnes, who tracked the Sir Henry Cecil-trained superstar through his career on the Newmarket gallops, focuses on some of the second wave of baby Frankels who are about to hit the track.

Swiss Storm (David Elsworth)
This powerful colt could debut at the Newmarket July course, just as his sire did six years ago, as he is entered in a 7f maiden there on Friday. A half-brother to smart sprinters Swiss Spirit and Swiss Diva, Swiss Storm is still part-owned by his breeders Lordship Stud but it is noticeable Elsworth himself has also taken a share. In a rare move, Elsworth boxed the colt to the other side of Newmarket for an early morning exercise on the Al Bahathri last week which left connections purring.

Rainbow Legacy (Sir Michael Stoute)
Stoute is yet to run any of his Frankels, but this strapping colt is the most forward and not far off a run. Entered in next year's Investec Derby, he is the only Frankel on the books of the Ballymacoll Stud and is bred to stay well as his dam is a full-sister to former Stoute-trained top-notchers Golan and Tartan Bearer. Rainbow Legacy has been pleasing in his work on the all-weather surfaces of late and can be expected to debut sometime next month over seven furlongs or a mile.
