In classic races on the flat and in the premier national hunt races all horses carry the same weight so weight is not a factor you need to consider when looking for winners. However, in many other races there are discrepancies in the weights carried that must be taken into account. In weight for age races these discrepancies are calculated to counterbalance the advantage that a more mature horse will have over a younger competitor.
A racehorse is not considered fully mature until he is aged four, therefore, when a younger horse takes on older rivals he is entitled to receive an allowance (a reduction in weight) in the race. This allowance depends on the month of the year, the age of the horse and the distance of the race. This is a tried and tested method for bringing together different generations of horses based on an official assessment of how the average young horse will catch up on his elders in terms of maturity as the months and years pass.
The key to this type of race is to find an improving three year old who has found his ideal conditions and is capable of defying the established differences and beating his older rivals.
Note: In the UK the official birthday of all racehorses is January 1st.
Below is the current scale of weight for flat and national hunt races.
