The Whittler System works on the idea that most horses after reaching their fifth year on the flat have seen their best days gone by.

With rare exceptions, their winning potential declines to such an extent that the expense of keeping them in training for another season cannot be justified. It is on the rare exceptions that this system is based.

There can be only one reason why horses of six years old or more are kept in training: and that is because their connections believe they can still win races.

Handicaps are the only type of race considered.

Flat racing only but not all weather.

Only horses aged 6 and over qualify.

To qualify the horse must be set to carry the highest weight of all the declared runners. Where two or more horses have been allotted joint top weight there is to be no bet.
