His other progeny included Workforce, Proclamation, Eishin Flash (Tokyo Yushun, Tenno Sho), Sajjhaa (Dubai Duty Free Stakes) and King's Apostle (Prix Maurice de Gheest).
Ridden as in all of his early races by Kevin Manning he started at odds of 4/1 and finished third of the fourteen runners, a length behind the Aidan O'Brien-trained winner Eagle Mountain.
Despite his defeat, the colt was then stepped up in class for the Group Two Railway Stakes over the same course and distance on 2 July and finished fourth behind Holy Roman Emperor, Drayton and Excellent Art.
He raced in second before taking the lead entering the straight and accelerated clear of his rivals to win by three and a half lengths despite being eased down by Manning in the closing stages.
[10] On 13 May, six days after his win at the Curragh, Creachadoir was moved up to Group One level as he was sent to France to contest the Poule d'Essai des Poulains over 1600 metres at Longchamp Racecourse.
He was overtaken in the closing stages and beaten half a length by the 33/1 outsider Astronomer Royal with Honoured Guest and Excellent Art in third and fourth.
[11] In June he was sent to England for the St James's Palace Stakes at Royal Ascot but failed to reproduce his best form and finished sixth of the eight runners behind Excellent Art.
In the late summer of 2007 Creachadoir was sold privately to Sheikh Mohammed's Godolphin organisation and was transferred to the stable of Saeed bin Suroor.
On his first appearance for his new owners the colt contested the Group Three Joel Stakes over one mile at Newmarket Racecourse on 6 October and started the 11/4 joint-favourite alongside the filly Tobosa.
[12] Two weeks later he was moved up in class and distance for the Champion Stakes over ten furlongs at the same track and finished fourth of the twelve runners behind the French colt Literato.
On his seasonal debut he started 5/1 joint second favourite for the Dubai Duty Free Stakes over nine furlongs on turf at Nad Al Sheba Racecourse on 29 March.
[16] Creachadoir was being prepared for a run in the Queen Anne Stakes at Royal Ascot when he broke his right foreleg in training and missed the rest of the season.
