A remarkable quirk in the barrier draw has seen the field for Saturday’s Group Two Rubiton Stakes at Caulfield drawn to correspond to their saddlecloths.

While greyhound and harness racing are always drawn this way, in thoroughbred racing, the number order is decided by several factors, chiefly the weight the horse is carrying.

The barrier draw is completely random and as such is not one of those factors, so the likelihood of every horse being drawn in a barrier to correspond to their number is very slim.

In fact, the possibility of this happening on a race with eight runners such as the Rubiton is 1 in 40,320, or 40,319/1. Those are similar odds to winning Division 3 in Tattslotto.

It’s hard to track how often this unusual this event happens, but the last time we could find it occurring in a major race was in the 2016 Caulfield Stakes, where there were just three runners. Winx won the race, wearing number 3, having jumped from barrier 3. 

Even in a race with a field that small there is only a 1 in 6 or 5/1 chance of the three horses drawing their corresponding numbers.

It remains to be seen whether the complete miracle result can be achieved and they can finish the race in racebook and barrier order. The odds of that happening in a random eight-horse race are about 1.6 billion to one.
