Ascot Draw Bias Explained

What the draw means (starting stalls)

The draw is the starting stall each horse is given. Stall 1 is the lowest number. In each race we split the field into three equal groups by stall: the low third, the middle third and the high third. The figures below show the share of runners in each third that won. Higher is better, and an even spread would be about the same in every column.

On Ascot's straight course, low numbers start on the far side and high numbers on the stands' side, nearest the grandstand.

The straight course: 5f to 7f

Trip	Races	Low stalls	Middle	High stalls
5f	105	6.2%	6.4%	8.8%
6f	147	8.0%	6.9%	7.8%
7f	125	6.7%	6.6%	8.8%

5 furlongs: high stalls have the best record (8.8% of runners won, against 6.2% from low stalls), and the pattern showed up in both 2019-21 and 2022-26. 6 furlongs: no clear edge to any third. 7 furlongs: high stalls again did best, but mainly in the 2022-26 races.

The round course: 1m to 2m

Trip	Races	Low stalls	Middle	High stalls
1m*	191	7.0%	8.6%	8.6%
1m2f	58	8.4%	11.7%	10.2%
1m4f	114	6.2%	9.6%	12.7%

* 1 mile includes both the straight mile and the round mile start, so read it as a mix.

1m4f shows the clearest draw effect at Ascot: high stalls won 12.7% of the time against 6.2% from low stalls, and it held in both periods. At 1m and 1m2f the spread is much more even. At 1m6f and 2m there are too few races (25 and 34) to say much.

Big fields v small fields

Here are the same trips in races with 14 or more runners:

Trip	Races	Low stalls	Middle	High stalls
5f	44	2.5%	3.0%	9.2%
6f	56	6.2%	5.0%	4.5%
7f	52	4.8%	4.5%	6.3%
1m*	46	3.9%	4.2%	4.9%

Over 5 furlongs with 14+ runners, the high third won 9.2% of the time against 2.5% from the low third (44 races, and the same story in both periods). That is the biggest draw split in our Ascot figures. At 6f, 7f and 1m in big fields the gaps are small.

Do the ground conditions (going) change the draw?

(New to the going? Read going (ground conditions) explained.) Half of these races (429 of 886) were on good to firm. On good to firm over 5 furlongs the high third won 8.3% against 4.8% low (58 races). On soft and heavy ground there are fewer than 25 races at any one trip, which is too few to trust a draw pattern either way.

How to use this

The draw is one piece of the puzzle, not the answer. Bookmakers know these patterns too, so a well-drawn horse is often a shorter price. Use the draw alongside form, ground and trip.
