250 years of the St Leger: how the world’s oldest Classic changed shape

From a 1776 sweepstake to Saturday’s 250th running, the race has been rebuilt four times over and never quite the same twice.
No Flat race in the world has run longer. On Saturday 12 September, Doncaster stages the 250th Betfred St Leger, a race first run in 1776 and still standing as the final Classic of the English season. Getting here took two and a half centuries of quiet reinvention.
This is not a preview of this year’s field. It is the story of how four things, distance, age, scale and standing, kept shifting under the same name.
How it began
The first St Leger went off on 24 September 1776 at Doncaster, a sweepstake for three-year-olds with a 25-guinea entry fee. The winner was a filly later named Allabaculia. The race took its name from Anthony St Leger, an army officer and politician who lived nearby at Park Hill.
It quickly became the last leg of the season’s Classic sequence and, alongside the 2,000 Guineas and the Derby, the final piece of the English Triple Crown.
Distance: shorter than it once was
The race has not always covered today’s ground. It was originally run over two miles, a genuine test of stamina even by the standards of the era. In 1813 the trip was cut to a mile and three quarters, closer to the modern shape of the race. Doncaster’s official distance today stands at an extended mile and six furlongs, still the longest of the five British Classics.
Age and the Triple Crown
The St Leger’s place as the season’s last Classic gave it a special role for the very best three-year-olds. Winning it alongside the 2,000 Guineas and the Derby completed the English Triple Crown, one of the sport’s rarest and most demanding achievements.
The crown at its peak
West Australian became the first horse to complete the Triple Crown in 1853, winning the Guineas, the Derby and the St Leger in one season. The feat would be repeated, but never often. Nijinsky, trained by Vincent O’Brien and ridden by Lester Piggott, took the 15th and so far last Triple Crown in 1970.
The closest miss
Since then only one horse has come within touching distance. Camelot arrived at Doncaster in 2012 unbeaten in the Guineas and the Derby, only to be beaten by Encke and leave the crown unclaimed for another year, and every year since.

Field size: the one gap in the record
How many horses actually lined up has varied enormously by era, shaped by everything from breeding fashions to the rise of rival autumn targets. Building an exact runner-count timeline needs a fuller pull from the official roll of honour, but the trend across the shift described below is consistent with a race that no longer commands the field it once did.
Status: losing ground to the Arc
For much of its history the St Leger stood as the undisputed end-of-season showpiece. That began to change through the 1970s and 1980s, as the Prix de l’Arc de Triomphe grew in both prestige and prize money.
Breeding increasingly rewarded speed over stamina, and connections of the best middle-distance horses started pointing at Longchamp, and later the Breeders’ Cup, instead of Doncaster. The Triple Crown, once a realistic seasonal target, became a historical curiosity rather than a plan.
Interruption and resilience
For a race with this much history, cancellations have been rare. The St Leger was called off only once in over two centuries, in 1939 with the outbreak of the Second World War, a stroke of bad timing that cost Blue Peter a shot at the Triple Crown.
The race returned the following year at Thirsk, then moved to Manchester in 1941 and Newmarket for three years from 1942 to 1944, before a final wartime stop at York in 1945.
Doncaster reclaimed the race in 1946, and all of the wartime runnings remain part of the official record. The race has left home twice more outside wartime, switching to Ayr in 1989 after subsidence closed Doncaster, and to York again in 2006 while the course was being rebuilt.
250 years, one name
Doncaster’s own framing is precise on this point. It is the 250th running by the course’s official reckoning, wartime substitutes included, rather than 250 unbroken years at home. That distinction matters to history, even if it changes nothing about what happens on the day.
The St Leger Festival runs from Thursday 10 to Sunday 13 September, with the 250th Betfred St Leger itself the Saturday centrepiece. Whatever the modern shape of the race, and however far its old Triple Crown status has faded, Doncaster in September remains the place where the oldest Classic in the world still gets run. Our Ebor Festival coverage tracks the rest of the autumn’s Flat calendar in the weeks leading up to it.
The 250th running, on 12 September 2026, went to Highwayman, trained by Joseph O’Brien and ridden by Saffie Osborne, in a renewal overshadowed by an injury to hot favourite Christmas Day.
