About the 1,000 Guineas and 1,000 Guineas betting
Unlike the 2,000 Guineas, which is open to both colts and fillies, entry to the 1,000 Guineas is restricted to fillies only. Other than that, the two races are very similar; both are for three-year-old horses only and are run over the straight course of Newmarket’s Rowley Mile over a distance of, as the name suggests, one mile.
The race is the youngest of the five English Classics, having been first run in 1814. Its main trial races are the Nell Gwynn Stakes, run over the same course and distance in mid-April, and the slightly shorter Fred Darling Stakes at Newbury, although neither of those race’s winners have outstanding records in the 1,000 Guineas itself.
Forty-six fillies have gone on to win the Oaks, although none since 2002 when Frankie Dettori won the race on Kazzia. Seven horses have won the “fillies Triple Crown” of the 1,000 Guineas, the Oaks and the St Leger.
Favourites have won 78 of the 194 runnings of the 1,000 Guineas, a 40 per cent success rate. The longest-priced winner was Ferry, which won at odds of 50/1 in 1918.
And perhaps unusually for a trainer who has dominated Group One horseracing in England in recent years, Aiden O’Brien has saddled only one winner (Virginia Waters, ridden by Kieren Fallon, in 2005).
There are various ‘1,000 Guineas’ around Europe, notably in Ireland, in Germany and in France (where it is known as the Poule d’Essai des Pouliches), all of which are modelled on the English 1,000 Guineas.
