St Leger Festival 2026: the four days, the numbers Doncaster keeps repeating, and a call in every race

The last Classic of the year, four days on Town Moor, and the biggest betting week of the autumn. The St Leger itself is at 3:35 on Saturday 12 September; the festival runs from Thursday 10 to Sunday 13. This page is our hub for the meeting: through the four days it carries odds compared across 20+ bookmakers for every race and OddsLens's call in every race, each one logged before the off and settled in public, exactly like the 5,625 calls already on the record. Below that, what our results database says about the course itself: 314 flat races at Doncaster since March 2025, favourites, the draw and the big handicaps.

The four days at a glance

Thursday 10 September
May Hill Stakes (Group 2) 3:35 · Park Hill Fillies' Stakes (Group 2) 3:00
Fillies' day. The May Hill over a mile for two-year-olds, the Park Hill over the St Leger trip for older fillies and mares, and the Weatherbys £300,000 two-year-old race at 1:50 — 17 entries for the biggest sales race of the week.
Friday 11 September
Doncaster Cup (Group 2) 3:00 · Flying Childers Stakes (Group 2) 2:25
The stayers over 2m2f and the two-year-old sprinters over five furlongs in the same hour. The Flying Scotsman (Listed) opens the card at 1:15 and the Leger Legends race at 1:50 brings back retired jockeys for a mile.
Saturday 12 September
St Leger Stakes (Group 1) 3:35 · Champagne Stakes (Group 2) 1:45 · Park Stakes (Group 2) 2:55 · Portland Handicap 2:20
Classic day. Sixteen entries for the Leger at the five-day stage, £396,970 in prize money, going good to soft as we write. The Portland, five and a half furlongs down the straight, had 36 entries and is the week's great puzzle.
Sunday 13 September
Sceptre Fillies' Stakes (Group 3) 3:05 · City of Doncaster Handicap 2:30 · Mallard Handicap 3:40
Seven races, six of them handicaps, five of those with 20 or more entries. Last year's Sunday saw no favourite win all afternoon.

Last year, race by race

The 2025 meeting ran Thursday 11 to Sunday 14 September, 31 races. Favourites won seven of them, which is a 23% strike rate against the course's usual 32%, and eight winners were returned at 10/1 or bigger. The features went like this.

The shortest-priced favourite of the week, Sweet William, won, and so did Scandinavia in the Leger. Almost everything else in the features was beaten, and the handicaps were brutal: Shazani at 40/1 in the Leger Legends race, Pathein at 28/1 in the St Leger consolation maiden, Devil's Advocate at 20/1 on the Thursday. Day by day the favourites went three from eight, two from eight, two from seven, and none from eight on the Sunday.

What Doncaster keeps repeating

One meeting is an anecdote. Here is the course over eighteen months: every flat race at Doncaster from March 2025 to August 2026 in our results database, 314 races and 3,105 runners at official starting price.

32.0%
Favourites' strike rate at Doncaster · 109 of 341
−4.5%
Return backing every Doncaster favourite · £1 level stakes
−11.4%
Same bet at every other flat course · 10,370 races

Favourites at Doncaster win about as often as anywhere else and lose you less. A 32% strike rate is the national picture, but the average Doncaster favourite goes off at 3.39 (a shade under 5/2) rather than 3.10, so the ones that win pay a little more. Backing every one of them still loses money, just less than half as much as the same bet elsewhere. That is not a system. It is a warning against the festival habit of ignoring the jolly because "big fields, big prices".

The draw on the straight course

Doncaster's sprint course is a straight, wide, flat mile, and the folklore says it is fair. The numbers say nearly fair, with a lean to the low stalls. We took every five, six and seven-furlong race with eight or more runners since March 2025, split each field into thirds by stall number, and counted the winners.

StallsRacesShare of runnersShare of winners
Lowest third15036.2%40.7%
Middle third15033.3%34.7%
Highest third15030.5%24.7%

Low stalls won about 12% more often than their share of the runners, high stalls about 19% less. That is a real edge and a small one. For comparison, the high third at Goodwood over the same period won 22% against a 33% fair share, which we wrote up in July. At Doncaster the draw is a tie-breaker, not a reason to back or bin a horse, and in the Portland's 20-plus runner field it matters less than where the pace is.

The big handicaps

The Portland, the City of Doncaster, the Mallard and the rest of the Sunday card are the reason a lot of people are at Doncaster in the first place. In our window Doncaster ran 44 flat handicaps with 14 or more runners, an average field of 16.8.

10/1
Average winning SP · 44 big-field handicaps
13 of 44
Winners returned at 10/1 or bigger · six at 20/1+
+13.5%
Backing every favourite in them · 13 wins from 52

Read that last number carefully before you act on it. Favourites in Doncaster's big handicaps have won one in four and shown a profit, on 44 races. That is a season and a half of data, not a law of nature, and one more Eternal Sunshine at 12/1 would dent it. What the 44 races do support is the boring conclusion: the winner of a 17-runner handicap is usually a 10/1 shot, sometimes the favourite, and almost never the 33/1 hunch. We measured the big-price myth across 179,202 runners; Doncaster is no exception to it.

Who wins here

Flat races at Doncaster since March 2025, trainers and jockeys with at least 15 runners and four winners. Strike rate is wins over runs; the return is £1 on every runner at SP.

The usual caution applies twice over. Thirty runs is a small sample, and the yards with the best strike rates here are the yards with the best horses everywhere; David O'Meara's 111 runners tell you who sends the most horses to Doncaster, not who to follow. Treat the tables as background, not as a reason.

How OddsLens has done at Doncaster

Since April 2026 the OddsLens model has made 98 calls at Doncaster, every one logged before the off with the best price at that moment. Twenty-six won, a 26.5% strike rate, for a +5.1% return at the logged prices and an average closing line value of +8.9%, meaning the price we logged was on average nine per cent bigger than the price the market closed at. Across every course the same record is 5,311 calls, 29.8% winners and a return of +0.5%. Ninety-eight is a small sample and a festival can turn it negative in an afternoon; if it does, you will see it on the same page as the good months.

An honest word about festival betting

Festival weeks are the hardest markets of the season to beat, and anyone who says otherwise is selling something. Doncaster in September has huge fields, ground that can go from good to soft between the Thursday and the Sunday, and a card built around handicaps designed to be impossible. OddsLens will make a call in every race anyway, because that is the deal: every race, logged before the off, losses left in. If it has a bad Leger week, you will see exactly how bad, next to everything else.

What you get during the festival, free: one race a day completely open, no account needed; every race's odds compared across 20+ bookmakers; OddsLens's call and the AI brief on every race with a free account; and the running public tally of how the week's calls are actually going.

Why trust a model at all?

Don't. Check it instead. Since April 2026 every top call the OddsLens model has made, 5,500+ of them, sits on a public ledger with the odds at the moment of the call and the official result. For context, backing every favourite over the same races lost about 10p per £1; we published that data too. We show the maths, not promises, and the record updates every evening through the festival.

Method. Doncaster figures cover every flat race at the course from 29 March 2025 to 15 August 2026 in the OddsLens results database, official returns, starting price, non-runners excluded. "Favourite" means the shortest starting price in the race; joint favourites are each backed for £1. The draw study uses races at 5, 5½, 6, 6½ and 7 furlongs (all on the straight course) with at least eight drawn runners; each field is split into thirds by stall number, so the low third holds the spare runner when the field does not divide by three, which is why the runner shares are unequal. Big handicaps are races with "handicap" in the title and 14 or more runners at SP. The 2026 card, times, entries and prize money are from the racing data feed on 8 September and may change at final declarations. The OddsLens record figures are as at 8 September 2026 and update daily on the record.
