Weight for Age
Weight for Age (WFA) is a term in thoroughbred horse racing which is one of the conditions for a race. HistoryThe principle of WFA was developed by Admiral Rous, a handicapper with the English Jockey Club. Rous experimented with weights until he arrived at a relationship between age and maturity, expressed in terms of weight. His original scale has undergone only minor alterations since his work in the 1860s.
