Craig an Eran's dam Maid of the Mist was a daughter of Sceptre and an influential broodmare in her own right, who also produced the Epsom Oaks winner Sunny Jane.

[5] On 29 April Craig an Eran (ridden by Jack Brennan) started at odds of 100/6 (approximately 16/1) in the 113rd running of the 2000 Guineas over the Rowley Mile at Newmarket Racecourse.

Humorist started favourite while the best fancied of the other 24 runners included Monarch (Middle Park Stakes), Alan Beck, Polemarch and Lemonora.

[9] Frank Bullock, who had ridden the colt in 1920, took over from Brennan when Craig an Eran was dropped in distance for the St James's Palace Stakes over one mile at Royal Ascot and won at odds of 1/8.

[14] Excuses were offered for the colt's defeat: it was reported that Taylor had been unable to train the horse to peak fitness on the prevailing hard ground and that Craig an Eran had been bumped by Westward Ho!

[7] Craig an Eran remained in training as a four-year-old but in April 1922 it was decided to retire the colt from racing and put him to stud at fee of 250 guineas.
