What is a Group One race?

In Britain, and the rest of Europe, a Group One race is a horse race of the highest calibre, as designated by the European Pattern Committee. Group One races include some of the most prestigious, valuable and historic races in Britain, over distances between 5 furlongs and 2 miles 4 furlongs, on Grade One racecourses, such as Ascot, Newmarket and York.

Some Group One races, such as the ‘Classic’ races – that is, the 1,000 Guineas, 2,000 Guineas, Oaks, Derby and St. Leger – are restricted to certain age groups and others, such as the Nassau Stakes and Sun Chariot Stakes, are restricted to a specific gender. However, generally speaking, horses of the same age and gender compete at level weights in Group One races, with weight-for-age and weight-for-sex allowances for three-year-olds competing against older horses and fillies and mares racing against colts and geldings, respectively.

Of course, Group One races can occasionally be downgraded; to maintain Group One status, over a three-year period, the average official rating of the first four horses home in the race in question must be 115, or more. From 2018, in Group One races, other than two-year-old races, in Britain, a horse must have achieved an official rating of 80 to be allowed to run in the first place.

Did the Derby used to be run on a Wednesday?

Yes, it did. For most of the twentieth century, the Derby was run on Epsom Downs on the first Wednesday in June. The race was staged on a Tuesday between 1915 and 1918 and on a Saturday between 1942 and 1945, when run, as the ‘New Derby’, at Newmarket, and on a Saturday again between 1947 and 1950, and in 1953, following its return to Epsom Downs. However, in the face of dwindling attendances, the last Derby to be run in its traditional Wednesday slot was the 1994 renewal, won by Erhaab, and since then the race has been run on a Saturday afternoon. The move was not universally welcomed and was subsequently described by various commentators as ‘a mistake’ or even ‘a catastrophic blunder’. Nevertheless, at one point, in the face of declining TV audience figures, a Saturday evening slot for the premier Classic was mooted by the racecourse executive at Epsom Downs.
