The Newmarket colt-based feature is one of the focal points of the season, as it usually yields us with horses to follow on their varying campaigns over differing trips - if we did not know who they were already from juvenile days.
This contest has been the starting point for many future stars of the game, none more so than the great Frankel who went to Suffolk for the second time on a five-race unbeaten run, after victory in the Greenham on his first start as a three-year-old.
Frankel went onto establish himself as one of the greatest horses of all time, as he bashed up everyone over the retained mile distance. He ended his career the undisputed champion of the world when succeeding first-time over ten furlongs in the Champion Stakes, retiring with a crown on his head for the late great Sir Henry Cecil.

As touched upon, the 2,000 Guineas is the opening leg of the Triple Crown for the colts, and Camelot was the last horse who went for the prized accomplishment let-alone managed to complete it.
Many three-year-old's make good use of their weight allowances against the older horses in some of Europe's biggest race including the Arc in France, and prefer to sidestep away from finishing their development in their respective Classic campaign, having matured earlier than others perhaps.
Some trainers may even believe their horses are the finished article, and need to go and challenge themselves again more experienced individuals to complete their scope.
Camelot trained by Aidan O'Brien proved his versatility by winning this back in 2012, before victory in the Epsom Derby later in June. He stepped up to 1m6f for the St Leger at Doncaster, for which he was sent off the 2/5f but could not reel in the Godolphin trained Encke.
In 2018, Saxon Warrior followed up his victory in the now-named Vertem Futurity Stakes at Doncaster, and went onto have many memorable clashes with John Gosden's Roaring Lion over a further distance.
If not continuing to race over a mile, many see the 2,000 Guineas as a real stepping stone for a horse's future career.
