The 2000 Guineas meeting at Newmarket - the home of flat racing, for many signifies the beginning of the turf season and the official end of the jumps season.
The changeover begins with the Guineas - the opening Classic of the campaign, which tests three-year-old's over the straight mile on Newmarket's Rowley Mile course.
It is the opening Group One of the flat season on any account, and acts as the opening leg of the Triple Crown for the colts, which is followed by the Epsom Derby and the St Leger at Doncaster.
The curtain raiser of the freshly new campaign, the champion and standout two-year-old's of the previous term usually meet and clash here first - although many may arrive off the back of a trial in the Craven or the Greenham, or in fact any other seven-eight furlong novice event.
The Guineas - won by some true greats in the years of old which we will discover below, gets things underway in the heart of the spring and sets the tone for the new season as the summer approaches.
