Weight-for-Age Races Explained

Weight-for-age (WFA) is a scale of weights that allows horses of different ages and sexes to compete on fair terms. Instead of handicap weights based on form, each horse carries a set weight according to their age and sex and the distance of the race. The scale is designed so that, in theory, a three-year-old and a five-year-old of equal ability would run the same. In practice, WFA races often favour certain age groups at certain distances, but the system is the fairest way to pit the best horses against each other.

Australia's premier weight-for-age race is the Cox Plate at Moonee Valley, run over 2040m in October. It has been won by many of the greatest horses in Australian racing history. Other notable WFA races include the Australian Cup, the Chipping Norton Stakes, and the George Main Stakes. WFA conditions are used in many Group 1 races so that the best can compete without the burden of big handicap weights.

Handicap races, by contrast, assign weights based on form: better-performed horses carry more weight. WFA races do not use form-based weights, so the top-rated horses often carry the same or similar weight. That makes WFA races a true test of class.
