The five Classics form the bedrock of the British Flat racing season and are the benchmark on which careers and legends are based. The Derby (pictured), the Oaks, the 2,000 and 1,000 Guineas and the St. Leger identify the best thoroughbred three-year-old colts and fillies of their generation.
The Classic season begins with the 2,000 Guineas over Newmarket's Rowley Mile in May. First raced in 1809, it's a straight mile dash on turf for colts and fillies. The race is the first leg of the Triple Crown, alongside The Derby and the St. Leger, but the feat is rarely attempted.
The great Frankel, ridden by Tom Queally, was the runaway 2,000 Guineas winner in 2011 during his 14-win unbeaten career.
Saxon Warrior gave Irish trainer Aidan O'Brien a record ninth win in the race in 2018. The jockey was O'Brien's son Donnacha.
The 1,000 Guineas is the fillies-only equivalent, raced the following day over the same Rowley Mile course at Newmarket in Suffolk, England. Billesdon Brook, trained by Richard Hannon, became the highest-priced winner in the race's history when she won at 66-1 in 2018.
