The most popular wining position/horse. The question of which post position has the most wins is not as simple as one would hope. There is no single answer for this, as it generally depends on a wide range of things like the distance, the nature of the surface or track. In some cases, particular tracks seem to have some sort of bias towards or against certain post positions. For instance, the post position number 1 in the Kentucky Derby has generally had a dismal win percentage. Some races might have inside post positions having a higher win percentage, while in others, the odds tilt in favor of the middle positions. A lot of thought and research has gone into finding the factors to consider when choosing the horse that is most likely to win. Generally, compared to the middle and inside track positions, the outside has a lower chance of delivering a win, but that is just about it when it comes to picking horses to win by numbers.
